Ingrown toenail: Causes, symptoms and treatment in Berlin
An ingrown toenail is painful and often gets worse without treatment. Here you can find out how to recognise it, what you can do yourself and when treatment is necessary. At the practice of Dr. Univ.-PD Amro Homssi, we treat ingrown toenails gently with laser, as an outpatient procedure under local anaesthetic.

What is an ingrown toenail?
With an ingrown toenail (medical terms: Unguis incarnatus or onychocryptosis), the side edge of the nail presses into the surrounding nail fold and grows into the skin. This causes pain, redness and swelling, especially when walking and in closed shoes. If the irritation persists, the area can become inflamed and form pus or proud flesh.
| Medical term | Unguis incarnatus, onychocryptosis (ICD-10: L60.0) |
|---|---|
| Most common site | big toe, side edge of the nail, often on both the inner and outer side |
| Who is affected? | all age groups, particularly common in adolescents and young adults |
| Main causes | nails cut too short or rounded, tight shoes, sweating, curved nails |
| To stop it growing in again | ablation of the lateral nail growth zone, by laser at our practice |
The 3 stages of an ingrown toenail
Doctors usually divide ingrown toenails into three stages. The stage determines which treatment is appropriate.
| Stage | Features | Recommended treatment |
|---|---|---|
| Stage 1 | redness, slight swelling, pain on pressure at the nail edge, no pus | foot baths, taking the pressure off, tamponade or tape, nail brace |
| Stage 2 | inflammation with pus, marked swelling, more severe pain | medical treatment; if the inflammation keeps coming back, ablation of the nail growth zone |
| Stage 3 | in addition, proud flesh (in German), i.e. granulation tissue growing over the nail edge; chronic course | surgical treatment, for example laser treatment or the Emmert procedure |
Causes of an ingrown toenail
- Incorrect cutting: Nails cut too short or with heavily rounded corners increase the risk of the nail growing into the skin.
- Unsuitable footwear: Tight or too small shoes, including sports and safety shoes, push the nail edge into the tissue.
- Sweating: Softened skin gives way more easily to the nail edge.
- Injuries: Knocks or crush injuries to the toe can cause the nail to grow in.
- Anatomical predisposition: Strongly curved nails, known as pincer nails, or a particular toe shape make ingrowth more likely.
Is an ingrown toenail dangerous?
In most cases, an ingrown toenail is mainly painful. Left untreated, however, the inflammation can spread. Possible consequences are nail bed inflammation, known as paronychia (in German), an inflammation of the surrounding tissue, known as cellulitis (phlegmon), and, very rarely, an infection of the bone. People with diabetes, circulatory problems or a weakened immune system are particularly at risk.
See a doctor immediately if a red streak runs from the toe up the foot, if you develop a fever, if the swelling increases rapidly or if you have diabetes and the toe is inflamed.
How do I recognise an ingrown toenail?
These signs suggest that your toenail is ingrown:
- Stabbing or throbbing pain at the nail edge, especially under pressure and in shoes
- Redness and swelling of the skin next to the nail
- The area is tender and feels warm
- Pus at the nail edge, a sign of infection
- Proud flesh (granulation tissue) at the nail fold
- The symptoms keep coming back
Ingrown toenail: what to do? Immediate measures in 5 steps
At an early stage, i.e. with slight redness and no pus, there is a lot you can do yourself:
- Foot bath: twice a day for 15 to 20 minutes in warm water with a mild disinfectant additive or a little soap. This softens the skin and nail and soothes the inflammation.
- Take the pressure off: Wear wide or open shoes, and avoid tight sports and safety shoes for a few days.
- Do not cut out the nail edge: Do not trim the nail in the corner. An edge cut too short often grows in again, and deeper.
- Keep it clean: Dry the foot thoroughly after the foot bath, treat the area with a wound disinfectant and put on fresh socks every day.
- Keep an eye on it: If the area does not improve after two to three days, if pus forms or if the pain gets worse, have a doctor look at the toe.
Which home remedies help and which do not?
- Useful: warm foot baths, wide shoes, taking the pressure off, wound disinfection, a small piece of tape that pulls the skin away from the nail edge.
- Only with guidance: pushing cotton wool or a tamponade under the nail edge. If done incorrectly, this injures the inflamed skin.
- Little evidence: tea tree oil, drawing ointment, vinegar or chamomile. They are no substitute for treatment once pus has formed.

When you should see a doctor
- if there is pus, severe swelling or throbbing pain
- if proud flesh forms
- if the symptoms do not improve after a few days or keep coming back
- immediately if you have diabetes, circulatory problems or a weakened immune system
Prevention: how to cut toenails correctly
- Cut straight across: Cut the nail straight across and do not round off the corners.
- Not too short: The corners should extend slightly beyond the skin.
- After a bath: Soft nails are easier to cut cleanly; straight nail clippers are better than curved scissors.
- Well-fitting shoes: about a thumb's width of space at the front, including in sports shoes.
- Dry feet: breathable socks, and change your socks after sport.

Which doctor treats an ingrown toenail?
Depending on the stage, different specialists are the right point of contact:
- Podiatrist: for mild cases without pus, for example for a tamponade, tape or a nail brace.
- GP or dermatologist: for the initial assessment and for treating inflammation in its early stages.
- Surgically active specialist: if the nail keeps growing in, or if pus or proud flesh forms. These are specialists in orthopaedics and trauma surgery, such as Dr. Homssi, or surgeons.
Do I need a referral? You do not need a referral for an appointment with us. A referral may only be necessary if your health insurance provides for a GP-centred care model.
All treatments compared
| Procedure | Suitable for | Anaesthesia | Healing | Risk of recurrence |
|---|---|---|---|---|
| Foot bath, tape, tamponade | Stage 1 | none | days to weeks | high, the cause remains |
| Nail brace (in German) | Stage 1, curved nails | none | worn for months | medium |
| Phenolisation (in German) | Stages 2 and 3 | local | 2 to 4 weeks, wound weeps | low |
| Emmert procedure (in German) | Stages 2 and 3 | local | usually 2 to 3 weeks, stitches | low to medium |
| Laser treatment | Stages 2 and 3, recurring | local | often 1 to 2 weeks, no stitches | low |
According to a Cochrane review, surgical procedures with ablation of the nail growth zone prevent recurrence better than non-surgical treatments. For mild cases, the nail brace remains a good choice.
Conservative, for mild cases
- Nail brace (orthonyxia): lifts the nail edge over weeks to months. More on the nail brace (in German)
- Tamponade and tape: relieve pressure on the skin at the nail edge.
Surgical, for inflammation or recurring symptoms
- Emmert procedure: the classic procedure, in which a wedge of the nail edge is cut out with a scalpel. Pros and cons of the Emmert procedure (in German)
- Phenolisation: The nail edge is removed and the nail growth zone is ablated chemically. Phenolisation and laser compared (in German)
- Laser treatment: The nail edge is removed and the nail growth zone is precisely ablated with the laser. This is our main focus. More on laser treatment

Modern laser treatment, our surgical focus in Berlin
In laser treatment of an ingrown toenail, the ingrown nail edge is removed in a targeted way and the corresponding section of the nail growth zone is precisely ablated with medical laser energy. The procedure is generally very gentle, with a small wound area and a short healing time.
- ✦
Precise and gentle on tissue
Only the affected part is treated; the healthy nail bed is preserved.
- ✚
Germ-reducing laser energy
The laser energy reduces germs and stops bleeding, which lowers the risk of infection.
- ⏱
Minimal downtime
Many patients return to their daily routine on the same day; closed shoes are usually possible after around 2 weeks.
- ◈
Outpatient at the practice
We carry out minor procedures as outpatient procedures at our practice, without a hospital stay.
Why laser treatment is our method of choice
The classic Emmert procedure is an established and proven method, and we also perform it. Which procedure suits you depends on the findings; we discuss this in the consultation.
| Classic Emmert procedure | Our main focusModern laser treatment with Dr. Homssi |
|---|---|
| Wedge-shaped excision with scalpel and stitches | Precise laser application with little bleeding |
| More bleeding during the procedure | Immediate control of bleeding through coagulation |
| Wound healing usually takes 2 to 3 weeks | Wound healing often within 1 to 2 weeks |
| Depending on the technique, a larger wound and longer aftercare | Laser energy reduces germs |
| Visible scarring possible | Small wound, discreet result |
| Proven, especially in advanced cases | Risk of recurrence low |
Ingrown toenail surgery: procedure, duration and anaesthesia
This is how laser treatment works at our practice in Berlin-Prenzlauer Berg:
| Where | outpatient procedure at the practice, no hospital stay |
|---|---|
| Anaesthesia | local, as a nerve block at the base of the toe (Oberst block); AR glasses for distraction on request |
| Duration | procedure about 15 to 25 minutes per toe, about 45 to 60 minutes including the pre-procedure consultation and dressing |
| Is the whole nail removed? | No, only a narrow strip at the ingrown edge |
| Stitches | none |
| Walking | straight after the procedure, in wide shoes |
| Driving | better not to drive yourself on the day of treatment |
| Showering | keep the dressing dry for the first 48 hours, then shower as normal |
| Work | office work often possible as early as the next day; for jobs that involve standing or walking, we discuss the length of time off individually |
Healing time and aftercare: what you can do again and when
| Period | What applies |
|---|---|
| Days 0 to 1 | keep the dressing dry, wide shoes, everyday activities at home possible |
| Days 2 to 7 | a short foot bath and a fresh plaster every day, office and school usually possible, follow-up check |
| Weeks 1 to 2 | wound usually healed, light sport and walks |
| Weeks 2 to 3 | closed shoes, jogging, football; swimming pool and sauna only once the wound has fully healed |
| after a few months | the nail has grown back slightly narrower at the treated edge; the aim is that it no longer grows in there |

Special situations
Diabetes and circulatory problems
With diabetes, wounds heal more slowly and inflammation spreads more easily. That is why you should have an ingrown toenail treated early. Laser treatment causes little bleeding and reduces germs, and it is well suited if your metabolic condition is stable. Nail problems in diabetes (in German)
Blood thinners
If you take blood-thinning medication, please let us know in advance. We will discuss with you whether and for how long a medication needs to be paused. Never stop taking it on your own.
Pregnancy
A local anaesthetic is generally also possible during pregnancy. If the procedure is not urgent, we often start with conservative treatment and plan the ablation for after the birth. We decide this together after the examination. More on ingrown toenails during pregnancy (in German)
Children and adolescents
With children, we start with conservative treatment whenever possible. Ingrown toenails in children (in German)
Athletes
Tight sports shoes and knocks during football or running make ingrown toenails more likely. After laser treatment, light sport is usually possible again after 1 to 2 weeks, and intensive sport after 2 to 3 weeks. Tips for football, running and ballet (in German)
What does treatment cost and what does health insurance pay?
| Treatment | Statutory health insurance | Private health insurance |
|---|---|---|
| Medical consultation at the practice | covered | covered, billed according to the German medical fee schedule (GOÄ) |
| Nail brace from a podiatrist | since 1 July 2022 as prescribed therapy (Heilmittel) on a doctor's prescription | depending on your policy |

Worried about the procedure? Audiovisual sedation with AR glasses.
At Dr. Homssi's practice, we use AR glasses (XREAL) for audiovisual sedation. During the laser treatment, you immerse yourself in a film, music or calming nature scenes and neither hear nor see what is happening.
- Audiovisual sedation: The AR glasses take you out of the treatment situation, visually and acoustically.
- Low pain and calming: Local anaesthetic and distraction noticeably reduce tension.
- For all age groups: Especially popular with patients who are anxious about treatment or have had negative experiences in the past.
- Companion welcome: You can bring someone you trust with you.

Frequently asked questions about ingrown toenails
What gives quick relief for an ingrown toenail?
At an early stage, warm foot baths with a mild disinfectant additive, wide shoes and taking the pressure off the toe can help. If pus or proud flesh forms or the pain gets worse, you should have a doctor look at the toe.
Can I cut out the ingrown nail myself?
We advise against this. Cutting it out can easily cause small injuries, and an edge cut too short often grows in again, and deeper. Cut your toenails straight across and have an ingrown edge treated professionally.
Which doctor is responsible for an ingrown toenail?
In mild cases, podiatrists, GPs or dermatologists can help. In the case of inflammation or recurring symptoms, a surgically active specialist is the right choice, such as a Specialist in Orthopaedics and Trauma Surgery.
Can an ingrown toenail heal on its own?
At an early stage, the symptoms sometimes subside with foot baths, taking the pressure off and cutting the nail correctly. However, if the nail keeps growing in or pus and proud flesh form, it usually does not heal without treatment.
Does a nail brace help with an ingrown toenail?
In mild cases, a nail brace can lift the nail edge over weeks to months and stop it from growing in. In the case of severe inflammation or recurring symptoms, it is often not enough. More on the nail brace (in German)
What is the best treatment for an ingrown toenail?
That depends on the findings: in mild cases, foot baths, taking the pressure off or a nail brace are sufficient. In the case of inflammation or recurrent ingrowth, ablation of the lateral nail growth is advisable. For this, we recommend laser treatment.
Which symptoms indicate that an ingrown toenail needs treatment?
Typical signs of unguis incarnatus are persistent pain on pressure at the lateral nail fold, redness, swelling, proud flesh (caro luxurians) and purulent discharge. At the latest when inflammation recurs or conservative measures (nail brace, tamponade) have failed, surgical treatment with laser matrix cauterisation is indicated.
Does health insurance cover laser treatment in Berlin?
Medically necessary surgical treatment of an ingrown toenail is generally covered by statutory health insurance. In Berlin, the laser method is mostly a self-pay or private service, as it goes beyond the standard benefits catalogue. It costs around €600 to €900 (depending on the extent; exact price after the medical consultation), billed according to the GOÄ.
Where is your practice for laser treatment in Berlin?
Our practice is located at Greifswalder Str. 137-138, 10409 Berlin. We are very easy to reach by public transport and treat patients from all over Berlin: from Mitte, Charlottenburg, Prenzlauer Berg and Kreuzberg to Steglitz, Zehlendorf, Pankow and the surrounding Berlin area.
Is an ingrown toenail dangerous?
In most cases, it is mainly painful. Left untreated, however, the inflammation can spread, for example leading to nail bed inflammation or cellulitis (phlegmon). If you have a fever, a red streak on your foot or diabetes, you should seek medical help immediately.
How long does it take for an ingrown toenail to heal?
At an early stage, the symptoms often improve within a few days with foot baths and taking the pressure off. After laser treatment, the wound has often healed within 1 to 2 weeks; after an Emmert procedure, usually within 2 to 3 weeks.
Which home remedies help with an ingrown toenail?
Warm foot baths, wide shoes, wound disinfection and tape that pulls the skin away from the nail edge. If there is pus or proud flesh, home remedies are no longer enough.
Does statutory health insurance pay for a nail brace?
Yes, since 1 July 2022, treatment with a nail brace from a podiatrist can be provided as prescribed therapy (Heilmittel) on a doctor's prescription. The prerequisite is an ingrown toenail that is suitable for this treatment.
How long are you signed off sick after toenail surgery?
That depends on the procedure and on your job. After laser treatment, office work is often possible as early as the next day. After an Emmert procedure, many people expect to be unfit for work for about three weeks, especially in jobs that involve standing or walking.
When can I do sport again after treatment?
After laser treatment, light sport is usually possible after 1 to 2 weeks, and jogging and football in closed shoes after 2 to 3 weeks. Swimming only once the wound has fully healed.
Which is better: laser, phenol or the Emmert procedure?
All three procedures ablate the lateral nail growth zone. Laser treatment is precise, causes little bleeding and requires no stitches. We will discuss which procedure is right for you after the examination.
Can an ingrown toenail be treated during pregnancy?
Yes. Conservative measures are possible at any time, and a local anaesthetic is generally possible too. We often plan non-urgent procedures for after the birth.
