I can only share my experience, but before I had even been diagnosed, my first symptom was an abscess that was deep in the skin. You couldn't see anything of it. It just REALLY hurt. It started out to feel like I had just been riding a bike for too long and my rear end was sore. It just kept getting worse to the point where I couldn't sit at all. If this sounds familiar and it doesn't go away, you may want to get it checked out.
