Hello,
Welcome to icliniq.com.
I read your query and can understand your concern. I have gone through the history and images provided by your end (attachments removed to protect the patient's identity).
It is plantar keratoderma which is extreme dryness and hardening of skin along with cracking of skin on the sole. They appear due to multiple factors, including genetic susceptibility, wherein there is a similar condition that runs within family and gets transmitted genetically due to climate conditions, dietary factors, use of harsh soaps or excess washing of the area, and as you have already mentioned the type of water as well. They may be managed but may recur if the medications are used consistently due to changes in the skin depending on the various external and internal factors.
My advice :
1. Soak your feet daily in warm salt water for 15 minutes in the morning and gently scrubbing the area with a pumice stone.
2. Aquaphor healing ointment to be used in the morning daily in a generous amount.
3. Urea 40% cream with Salicylic Acid and Hyaluronic Acid to be applied at night on the affected areas. They may be continued till the area softens.
4. Avoid shower gels and soaps.
5. Oilatum bath formula of three full bottle cap in 1 liter of water may be used for soaking feet in them for five minutes and washing the area as well at night before applying the cream as mentioned above.
6. Avoid oily and fried food, sweets, and red meat. Make sure to include more fish and at least 12 glasses of water a day for hydration.
7. Capsule Omega-3 once daily after breakfast to be consumed for two months for moisturization.
8. Capsule Evion 400 or vitamin E capsule 400 mg to be consumed at night after dinner for two months for hydration.
9. After using Urea cream at night, wear comfortable socks after 20 minutes of applying the cream to ensure they are well absorbed.
Continue these medications till the area becomes softer.
However, please consult a physician, discuss with them and start taking the medications with their consent.
I hope this helps.
Thank you and take care.
