Abnormalities of the skin on the soles of the feet?

There are three abnormal areas on the skin of the sole of the foot, as shown in the images: https://imgur.com/QpaPhQ2 https://imgur.com/HRR6Eo2 https://imgur.com/niEAbXI.
The skin near the foot bones has been persistently inflamed, and recently, there has been irregular thickening and severe keratinization of the skin on the sole.
Some parts of the skin on the foot are sometimes very itchy, with flaky skin that feels hard enough to cause a stabbing sensation when walking.
Additionally, the skin appears somewhat similar to being cut by a knife.
What skin condition could this be? Would topical ointments be effective? Thank you.

More Info

Understanding skin abnormalities on the soles of the feet can be quite complex, as various conditions can manifest with similar symptoms. Based on your description, it sounds like you may be experiencing a combination of inflammation, hyperkeratosis (thickening of the outer layer of the skin), and possibly a fungal or dermatological condition.

Possible Causes
1. Psoriasis: This is a chronic autoimmune condition that can cause red, scaly patches on the skin. It can affect the soles of the feet, leading to thickened skin and discomfort. The itching and the sensation of being "cut" could be related to the buildup of skin cells.

2. Eczema (Atopic Dermatitis): This condition can cause inflamed, itchy skin. If you have a history of eczema, it could flare up in response to environmental factors, such as changes in climate or exposure to irritants.

3. Fungal Infections: Conditions like athlete's foot (tinea pedis) can lead to scaling, itching, and inflammation. Fungal infections often thrive in warm, moist environments, making the feet particularly susceptible.

4. Calluses or Corns: These are areas of thickened skin that develop in response to pressure or friction. They can become painful and may crack, leading to discomfort while walking.

5. Contact Dermatitis: This occurs when the skin reacts to a substance it has come into contact with, leading to inflammation and irritation. This could be due to soaps, detergents, or even certain types of footwear.

Treatment Options
1. Topical Treatments: Depending on the diagnosis, topical corticosteroids can help reduce inflammation and itching. For psoriasis, stronger topical treatments like vitamin D analogs or retinoids may be recommended. If a fungal infection is suspected, antifungal creams would be appropriate.

2. Moisturizers: Keeping the skin well-hydrated is crucial, especially if you are experiencing dryness and scaling. Look for thick creams or ointments that can help lock in moisture.

3. Footwear: Ensure that you are wearing comfortable shoes that do not cause friction or pressure on the soles of your feet. This can help prevent the formation of calluses and corns.

4. Soaking and Exfoliation: Soaking your feet in warm water can help soften thickened skin. After soaking, gently exfoliate with a pumice stone to remove dead skin.

5. Avoiding Irritants: If you suspect contact dermatitis, try to identify and avoid any products that may be irritating your skin.

6. Consultation with a Dermatologist: Given the complexity of skin conditions, it is advisable to consult a dermatologist for a thorough examination and accurate diagnosis. They may perform a skin scraping or biopsy to determine the exact cause of your symptoms.

Prevention
To prevent future flare-ups, consider the following:
- Maintain Good Foot Hygiene: Regularly wash and dry your feet thoroughly, especially between the toes.

- Use Protective Footwear: In public places like pools or gyms, wear flip-flops or water shoes to prevent fungal infections.

- Moisturize Regularly: Apply a good moisturizer daily to keep the skin hydrated and prevent cracking.

- Monitor for Changes: Keep an eye on any changes in your skin condition and seek medical advice if symptoms worsen or do not improve with home treatment.

In summary, while topical medications can be effective, the key to managing skin abnormalities on the soles of your feet lies in identifying the underlying cause. A dermatologist can provide a tailored treatment plan to address your specific condition.
