Foot Skin Issues: Causes of Holes and Pain - Dermatology

Share to:

Recently, there are many sores on the soles of my feet?


There are many small holes on the soles of my feet.
A few days ago, they were just red, and I would feel pain after walking a bit more than usual.
However, after taking a shower today, they suddenly turned into many small holes, which looks quite unpleasant.
I didn't have any symptoms before this; the only change recently has been an increase in my basketball playing frequency, but nothing else is different.

Hello: Based solely on the textual description, it is not possible to accurately diagnose a skin condition.
Recently, with the hot, humid, and sultry weather, it could be plantar tinea pedis (athlete's foot).
If the skin condition does not improve or worsens, it is advisable to consult a nearby dermatologist for diagnosis and treatment.
Thank you!

More Info


The symptoms you are describing—small holes in the soles of your feet, redness, and pain after increased activity—could be indicative of several underlying conditions. Given the sudden appearance of these holes and the associated discomfort, it is essential to consider a few potential causes and their respective solutions.


Possible Causes
1. Fungal Infections: One common cause of skin issues on the feet, especially if you have been more active (like playing basketball), is a fungal infection such as athlete's foot (tinea pedis). This condition can lead to skin peeling, redness, and sometimes the formation of small holes or fissures in the skin. The increased moisture from sweating during physical activity can exacerbate this condition.

2. Blisters: If you have been wearing shoes that do not fit properly or if you have been engaging in activities that cause friction on your feet, blisters can form. When blisters burst or are popped, they can leave small holes or open areas that may become painful and red.

3. Hyperhidrosis: Excessive sweating of the feet can lead to skin maceration, making the skin more susceptible to infections and irritations. This condition can also contribute to the development of small holes or fissures.

4. Dermatological Conditions: Other skin conditions, such as eczema or psoriasis, can cause similar symptoms. These conditions may lead to dry, cracked skin that can develop holes or fissures, particularly on the soles of the feet.

5. Pressure Ulcers: If you have been standing or walking for extended periods, pressure ulcers can develop, especially if there is inadequate blood flow to the area. These can appear as small holes or sores.


Recommended Solutions
1. Consult a Healthcare Professional: It is crucial to seek medical advice from a dermatologist or a podiatrist. They can provide a proper diagnosis and treatment plan tailored to your specific condition.

2. Keep Feet Dry and Clean: Ensure that your feet are clean and dry. After washing, thoroughly dry your feet, especially between the toes, to prevent fungal growth.

3. Use Antifungal Treatments: If a fungal infection is suspected, over-the-counter antifungal creams or powders can be effective. Apply these as directed, and ensure to continue treatment even if symptoms improve.

4. Proper Footwear: Make sure you are wearing well-fitting shoes that provide adequate support and reduce friction. Consider using moisture-wicking socks to keep your feet dry during physical activities.

5. Avoid Irritants: If you suspect that certain soaps, lotions, or detergents may be irritating your skin, try switching to hypoallergenic products.

6. Moisturize: If your skin is dry, use a good moisturizer to keep the skin hydrated. This can help prevent cracks and fissures from forming.

7. Rest and Elevate: If your feet are painful, try to rest and elevate them to reduce swelling and discomfort.

8. Monitor Symptoms: Keep an eye on the condition of your feet. If the holes worsen, become infected (showing signs of pus, increased redness, or swelling), or if you develop fever or systemic symptoms, seek immediate medical attention.

In conclusion, the appearance of small holes in the soles of your feet, especially following increased physical activity, warrants careful attention. By understanding the potential causes and implementing appropriate measures, you can address the issue effectively. Always prioritize consulting with a healthcare professional for personalized advice and treatment.
