Hi,Dear,
Thanks for the query to HCM. I studied your problem in depth and I understood your concerns.
Cause and plan of Treatment-
In my opinion on the given data,you seem to have
bruise with
cellulitis around it due to infection of the bruise.Its not getting better due to the friction at the butt crack between 2 butt cheeks.
Treatment-Consult ER Surgeon / and take anti-inflammatory / and antibiotics for 5 days time, and this would resolve the issue of the lump on buttocks.
Plz check out with your ER Surgeon who would treat it accordingly.
So don't build up wrong concepts and self medicate your self which would increase risks and costs to you.
Instead just ask a query to HCM and be comfortable to resolve your health issues.
Welcome for any more query in this regard to HCM.
Write good reviews and Click thanks if you feel satisfied with my advise.
Have a Good Day.
Dr.Savaskar M.N.
