Soles of feet are red, tender look swollen. Hard and peeling skin on the back of toes, hard skin and sore. Used athletes foot 5 days didn't help?

Tinea Pedis. It sounds like a tinea pedis or athletes foot. Fungus can be very resistant to medication. Put lotrimin (clotrimazole) AF cream as well as hydrocortisone cream 15 three times a day for a week. Also, dry feet and toes carefully, then apply gold bond powder into your socks immediately after bathing or swimming. Good luck.
