Welcome home. I hope you recovery goes as well as your surgery. As I recall, your surgeon's plan was to follow the sciatic & pudendal nerves and remove any scar tissue (fibrous tissue) pressing against the nerves. Do you think the scar tissue is from a bad fall many years ago?
Your surgery reminds of Sue in Belgium, who had bilateral surgery to remove multiple fibroids pressing on the sciatic nerves. I wonder how many cases of Piriformis Syndrome are really caused by adhesions or scar tissue pressing on the nerve. And then maybe the muscle spasms trying to protect the nerve, but it just increases the pain. Who knows?
What kind of test showed you had scar tissue in these areas? Also, I can't wait to hear what, if anything, the doctor did to
the piriformis muscle. And to see if this surgery decreases your pain long term. Best wishes, Mary
