I first spotted a round crusty ringworm like rash under my arm & thought it was ringworm. I quickly scrubbed it with lime in an attempt to prevent it from spreading. Few days later I noticed another patch of same looking rash on my breast which was extremely itchy and scratched it. It began to spread very quickly leaving dark patches everywhere it appeared. It's been three weeks since and now covered in this rash that has engulfed my whole body and seems to be spreading with a venom. Am not sure what this is as I've never had it or seen anyone with it's kind. The itching is driving me crazy. Pls help!!!
