I have had a type sciatica for the last 6 years. It seems to originate from my buttock and so, 18 months ago I was diagnosed from my symptoms only and a consultation with an Ortho specialist as having piriformis syndrome. I had some physio treatment which really helped but the problem didn't really go away, I just got to the point where I could live with it.
Last April, it flared up again, big time. I went back to physio and relief was very temporary (minutes) and also had acupuncture etc. I was considering seeing another consultant (reasons as to why I did not go back to see the original one) and the symptoms eased, again not really going away) Two weeks ago I saw another consultant who sent me for an mri on my lower back as he said that the most common place for the nerve to be irritated is there. He said that the reason I have no back pain is because the pain is referred to my buttock and then down my leg. I was amazed to find that he had not asked for a scan of my piriformis as this was in the equation. The scan showed that one of my vertebra was mis-aligned and could be the reason I am having problems. He now wants to do an injection into the spine and I am aware that I asked his opinion but I still think the problem is with the piriformis muscle and think what he wants to do is by injecting is to rule it in or out. However, I am not sure that is necessarily going to prove anything unless my symptoms improve as I am aware that these injections do not always work first time.
Moreover, if you look at my buttocks and compare one to the other, the affected one, around the site of the pain has a large dimple, as if there is no padding under the flesh. The other one is very rounded. Does anyone think this suggests that there is a problem with the muscle underneath that area?? To be honest, I haven't brought this to his attention but thought he should have noticed himself. I think this is quite a serious measure to just rule something in our out.
