In May 2012 ( no photo of this) I was had a pilonidal abscess that wasn't very visible ( no lumps) and just put me in excruciating pain. After visting my GP I was referred to a surgeon where it was lanced/drained and was packed for a little more than a week do open wound healing. The open would left was about the size of a golf ball but healed with no complications. However in May 2015, 3 years later, (first top left photo) it flared up. You can see the scar from the lancing. The pain returned but there still wasn't any visible sign of the abscess. I did not see a doctor during this time. I took curcumin and cleaned it well/ applied heat and the pain went away. Also I didn't have any drainage. Then around Janurary 2016 a visible red lump appears in the second photo. It seems like it's at the same site as before. I again took the curcumin as before and the infection and pain went away after about a week. I also experienced NO drainage which seemed weird. (The third photo on the bottom left shows the cyst after The pain went away) However a couple weeks later a tiny pit formed and now March 1, 2016 (the last photo-taking in diffenent lighting which is why it appears more yellow) there is a large pit that is getting bigger! I am experience no pain but am concerned with what will follow. It doesn't seem to be draining or anything. I never had a pit like this before this large. I'm trying my best to avoid it stretching out anymore. I'm afraid of debris getting in it and becoming infected. Should I be concerned? How should I clean it specifically? Will it eventually get smaller or go away? Thanks for reading and your insight in advanced!
