Hello,

My father is a 73 year old male with Parkinson's, having been
diagnosed in 1996. He is not athletic. Since August 2006 he has has a
tremendous pain in his right buttocks. This pain has migrated down
his right leg to almost the ankle. The most significant leg pain is
on the shin.

I'm not certain what everyone knows about Parkinson's here, but he
twitches tremendously when the medication is not working. His
twitching and pain are both focused on the right side.

He has been to many docters (Neurologist with Parkinson's specialty,
rheumatologist, orthopaedist, urologist, proctologist, general
practioner). Most are stumped about the butt pain. The Parkinson's
doctor believes that it is the result of parkinson's. The
orthopaedist though somewhat stumped, finally diagnosed it has
Piriformis Syndrome. He recommended physical therapy. My father
went for a few weeks and then promptly quit thinking it was a waste
of time.

The Rheumatologist ruled out significant arthritis. No prostate
cancer.

He had a pelvic MRI that showed nothing. He has had bone scans, x-
rays, Sed tests of blood, and many other things that I cannot
remember. I had a hydrocortisone shot to relieve pain, but it did not
help.

My questions for the group are:

1. Does Piriformis Syndrome occur in Parkinson's patients that are
not voluntarily active, but involuntarily active.

2. Tests to further pin down the diagnosis?

3. Steps to alleviate pain.

Thank you.

John
