| | Re: Possible Piriformis Syndrome
Ii usually post on the back board where we talk about piriformis issues from time to time. You might be able to get some additional information there.
There are many issues for the type of symptoms you are feeling. It could be a lower lumbar disc, or a problem with the sacroiliac joint. At least in my experience, it is a bit unusual to have a problem only with the piriformis without having any other issues with the lumbar spine or SI joints.
Is the pain only on the back of your thigh and leg? Where does your foot go numb? Do you have any tingling? Numbness and tingling are usually a sign that there is some spinal nerve compression. But the sciatic nerve itself can get pinched if the piriformis is taut or inflamed. In this case, the question would be "what is causing the piriformis to be taut or inflamed?
There are some provocative stretches you can do to help determine if it is the piriformis that is causing the pain. I think you can find them online if you look through a number of different websites.
