I have a small round bump on the outside of the labia just next to my leg, basically in the crease of my leg. It first came up about a year ago after shaving and formed a head. It popped on its own and I put neosporin on it and it went away a few days later and completely healed . After about five months a smiler bump appeared in the exact same spot and looked almost exactly the same. I only noticed it this time because it was painful to the touch. This time it also upon applying pressure made a dark purple color just the skin and would pop and leave a fairly decent sized hole in the skin with dark blood and pus mixture. But then it healed very quickly, like overnight quickly. The same thing occurred several more times, it would appear and heal and reappear and heal before I could even make an appointment to see a doctor. All several weeks apart in the same spot. Now there is a little scar tissue area but it looks like it has reappeared again after the longest of it not appearing almost 8 months later. I am worried and don't know what it could be. I have never been sexually active with anyone at all so that takes out STIs as I haven't had any sexual partners ever. It feels like like a small round almost ring-like bump with pressure around the outside and a softer area on the inside and the size of a small fingernail. Any ideas about what it could be? I have assumed this who time thats it just an infected hair follicle. Any ideas?
