I have a patch of swollen skin, kind of like a skin tag. Sometimes it gets flat and I don't notice it, but other times it flares up and when my underwear are tight it irritates it more. It's right in the crease of my leg, near my vagina. I've been putting coconut oil on it, and it started shrinking and it's almost flat now. Except I was looking at it and there is a hole right in the middle, when you pull the skin tight, it's easier to see. I dont know what it is, I've had it for a while. At first I thought it was an STD but all the people I've slept with, at least the ones I kept in contact with, are clean... So i dont know what it is, any ideas? Maybe it's a cut that never healed?
