Red Dots Under Thick Skin: Is It Athlete's Foot? - Dermatology

More Info

---

Based on your description of red dots under thick skin on your foot, it is essential to consider several factors to determine whether this condition could be athlete's foot (tinea pedis) or another skin issue. Athlete's foot is a fungal infection that typically affects the skin between the toes and on the soles of the feet. It can cause symptoms such as itching, burning, and peeling skin, but it may not always present with visible redness or dots.

The presence of small red dots under thickened skin could indicate several possibilities:
1. Fungal Infection: Since you mentioned having previously used antifungal medication (Lamisil), it is possible that the thickened skin is a result of a chronic fungal infection. Fungal infections can lead to skin changes, including thickening and discoloration, and sometimes small red or inflamed areas can appear as the skin reacts to the infection.

2. Warts (Verrucae): Warts are caused by the human papillomavirus (HPV) and can sometimes present as small red dots or bumps under thickened skin. They often have a rough surface and can be painful if located on weight-bearing areas of the foot. If you suspect warts, they typically do not appear as red dots initially but can become more prominent as they grow.

3. Calluses or Corns: Thickened skin can also be a result of friction or pressure, leading to calluses or corns. These areas may have small red dots due to irritation or inflammation but are generally not indicative of a viral or fungal infection.

4. Other Skin Conditions: Conditions such as psoriasis or eczema can also lead to thickened skin and red spots. These conditions often have additional symptoms, such as itching or scaling.

Given that you have already completed a course of antifungal treatment and are still experiencing these symptoms, it would be advisable to consult a dermatologist or a podiatrist. They can perform a thorough examination and possibly a skin scraping or biopsy to determine the exact nature of the red dots and the thickened skin.


Recommendations:
- Avoid Self-Surgery: It is not advisable to attempt to cut or remove the thickened skin or the red dots yourself, as this can lead to infection or further complications.

- Keep the Area Clean and Dry: Maintain good foot hygiene by washing your feet daily and ensuring they are thoroughly dried, especially between the toes.

- Use Antifungal Powder: If you suspect athlete's foot, using an antifungal powder can help keep the area dry and reduce moisture, which is conducive to fungal growth.

- Consult a Specialist: A healthcare professional can provide a definitive diagnosis and appropriate treatment options, whether it be antifungal therapy, cryotherapy for warts, or other interventions.

In summary, while the symptoms you describe could be related to athlete's foot, they could also indicate other skin conditions. A professional evaluation is crucial for accurate diagnosis and effective treatment.
