for the past two years i have been getting a recurring rash/scab on my butt. it starts out like a mesquito bite then spreads to the size of a half dollar. it itches and after a few days its scabs and heals like normal. its also a little painful before it scabs.
Hello, I read carefully your query and understand your concern. Your symptoms seem to be related to a BS related to eczema. I suggest using a steroid cream for local application such as HY Chat Doctor.  I also suggest using anti histamine such as Loratadine 10 mg daily. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!
