I had pilonidal cyst but never went to the doctor and it drained by itself but it left a brownish color instead how can i get rid of it?

Surgery: Pilonidal cysts are generally only cured by surgical excision of the area, and can recur however uneven if this is done. See a surgeon with experience in pilonidal disease for a consultation to find out more. Hope this helps!

Only definitive: method is surgical excision of pilonidal cyst. Consult with a surgeon, but you might want to accept discoloration in this location instead of operation.
