Just before Xmas I had a treatment with an Osteopath to rectify my pelvis, that I believed had tilted slightly because I had been doing too much hoovering. (I have had problems with my pelvis in the past when it completely locked and left me hobbling around and it was osteopathy that put it right.) Because I was 9 weeks pregnant at the time he didnt push it back into place, more gentle manipulation that seemed to sort it out. Only from the day after I became aware of a very tight muscle in my right bottom cheek which was so uncomfortable after getting up when I had been seated for a while. When I am stood up, I hardly feel it but it is most uncomfortable sitting down and getting in and out of the car. In between Xmas/New Year I returned to the Osteopath with my complaint of a pain in the bum and he did some stretching on my legs but it was hard to pinpoint with touch where the pain was actually was. He wasnt 100% sure it was my piriformis muscle but explained how that area is connected from the bottom of the pelvis to the hamstring and I have been getting pains down my hamstring and the back of my calf. The treatment didnt do anything to relieve the pain which was become extremely frustrating. When getting into bed and laying down on my back I nearly hit the roof when I lay on that area of my bottom! I've since seen another Osteopath who I normally go to when my pelvis plays up. He was away over Xmas which is why I went elsewhere. He said he doubted it was the piriformis muscle as I would have felt it when he touched that area, and that he was sure it would ease off considerably now he'd straightened my pelvis which he said was an inch out. Only the info I have read up on says that the muscle is deep in the bottom and hard to locate? Its now 3 days since he saw me and it is still no better? I'm sick of looking like an old woman stooping over when I get up from my chair. I'm a massage therapist myself and am very tempted to use my vibratory massage machine over my bottom to see if that will help loosen it up. I've been referred to a physio by my doctor but that could take weeks. She just advised a hot water bottle on it. I just want someone to tell me whats wrong with me. can anybody help??
