Hello,
The hand symptoms can be due to a fungal infection. Most cases of fungal infections respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine,ketaconazole and clotrimazole.You can consult a pharmacist and get any cream or lotion containing these ingredients. Some of them are Lamisil, Monistat derm, Mycelex, and Nizoral.
If the symptoms persist then pls consult a dermatologis as oral antifungals may be needed.
Hope it helps.Take care and pls do keep me posted on how you are doing and if you have any additional queries.Kind regards.
Cheripompholyx is some times related to fungus.Treat with mild steroid creme applied externally.
