I have a burning itchy patch of skin above my anus. i have tried neosporin, tucks, bag balm, and corn starch. i am very clean but it hasn't cleared up. it's been several months?

Time to have it examined and treated properly. Best to start with your primary care doc, among many others a fungal infection and/or skin condition, such as eczema, will have to be ruled out, avoiding friction and keeping area dry should help.

It is not feasible to provide a meaningful opinion without additional history, and physical examination. It may be a pilonidal cyst.
