I got this off the web search and it pretty well says what I have...I
never had a real name for it....but this nerve in my buttocks is
defently just like this discribes......
Piriformis Syndrome
The piriformis is a small muscle in your buttock, which has many actions
to help movement to occur at the hip. The sciatic nerve is a large nerve
that travels from the lower back and down the back of the leg to supply
lots of muscles in the leg and foot. The sciatic nerve passes underneath
the piriformis muscle so if this muscle is tight or injured, it will
pinch the nerve and cause pain, tingling, or numbness in the buttock and
down the rest of the nerve path. These symptoms may be more obvious
during activities such as squatting, sitting, running and lifting heavy
objects.
A physical therapist can help to teach you how to decrease your pain and
increase your healing. After the initial injury is healed, a physical
therapist can teach you how to stretch your piriformis muscle and other
muscles that can be pinching the sciatic nerve. The physical therapist
can also decrease your risk of developing "sciatica" again by teaching
you what positions and movements that should and should not be
performed.

I did a scaitic nerve search on yahoogroups and it gave me this
group....Im glad you gave your option on his book though....I can send
it back unread when it comes this week........my repressed anger is when
Ive eaten a few too many fresh baked Choc..chip cookies...:>)....BonnieW
