I really pray this helps someone. Drs did biopsy. Skin scrapes all negative. Aunt had exact same thing 20 years ago she went through exact aame thing with drs. All her test came back neg too. She couldnt remember what an older doctor finally Prescribed but she said it stunk so bad. And she had to use it everyday head to toe along with her husband and mother.I told her what I mixed up and seems to be same ingredients her and her family used. The mix that I mixed up didnt really seem to be working the first 3 weeks but the last week when I finnally stopped there was nothing no biying itching or crawling.
