For about three years I have had a reoccurring cyst on my groin. The cyst is always in the same place, and I can't find any pattern to why or when it appears. I've been treated with antibiotics for months at a time, and eventually have to have the cyst drained. However, it ALWAYS comes back. It never forms a head, and it's extremely painful. To the point where if it gets big enough I'm not able to walk or move my leg at all. It doubles in size over night. Need to find something to keep it from coming back!
