Cracked Heel With Cuts And Bruises Due To Scratching The Foot, Severe Itching, Rashes On Body. What Could This Be?

I think I have a case of Athletes foot. However without paying attention I ve itched it over and over, snowballing it for weeks into a very painful cracked, skin peeling, cuts and bruises and I believe I ve made my feet swollen from it. I m using Lotrimin cream now, for the last week. I thought I saw minor improvements however I started itching again, causing more cuts, I stopped that ( it s hard not to itch! ) I m getting a rash over my body now, I think its from the cream. I really would rather not go to the doctor as of yet, I know I should, I m stubborn! Any other tips for me? Besides see my doctor..
