The following is from a friend who has sciatica & PD >>1/22/98 As a sufferer of sciatic pain and Parkinson's, I offer below a history that others may profit from it. About 4 years ago, in addition to my Parkinson's symptoms, I developed sciatica. If I walked. ran or stood still for 10 minutes, the pain returned, The following is a rough schedule of treatments I went through and theri results: Two subdural injection treatments with procaine and steroids first in lumbar 5, second in lumbar 6. Pain relief for 7 days after each treatment. Nine chiropractic treatments. Zero relief. Three courses of physical therapy. Got stronger but no changes of pattern. Sciatic pain began 10 minutes after each sequence. part 2 I asked my anesthesiologist what this all meant. "It means we were all in the wrong places." I then suggested that we try to find the location of the injured nerve by putting a long thin needle down in the foreman and icject a small dose of procaine. If I walk more than ten minutes, it meant that we found the place. He tried 4L and 2S. Number 2 sciatica produced relief of pain for at least 40 minutes after the injection. The next step is to decide what to do for the vertebra (No. 2). It could mean a heavy dose of steroid to see if we can pass the seven-day limit. Or revisiting the surgery suite. I'll keep you posted. PS Feb. 8 Since writing this letter the anesthesiologist thinks he has the nerve involved.<<<< Hope this is helpful. Regards, Ken Aidekman Fund the Research. Find the Cure.
