I waorked as a Chiropractic assistant for two years and surgery is NOT the only option. Go see a Chiropractor and get some deep massage after the treatments and it will diminish. Also, get a tennis ball, (a new hard one) put it right into that area on your butt and kindof roll it in a circle to increase and stimulate the blood flow. Also, your Chiropractor can treat you with EPS = Electrical Pulse stimulation and that will help. The key is to get the blood flow moving and to massage out the old blodd that is accumulating there.
