Hi Everyone, The list serve is wonderful but it is also taking a fair chunk of time to read through it, and more to fully take it in. But at least I've learned Downloading 101 and where to convert it on my machine so I can peruse the whole thing! I am among those who believe that trauma to the nervous system esp. the brain often triggers PD or PD-like symptoms. If I understand what you mean by secondary PD, I believe this is my situation too. I have been contemplating tonsollectomies as a possible culprit in one early apparent symptom. I have always been a "gagger" e.g. when doctor wanted to look at throat and especially when eating. I have always been a slow eater becuz I pulverized my food by chewing, esp. real solid meats and the like. I have also contemplated sinus trouble as another precursor. I 've contended w/that and of course, it affected my sense of smell. Possible whiplash in a minor auto mishap followed by probable soft tissue and nerve damage to my r. side from 3 separate insults to my hand/arm/neck/shoulder, all in the early '80s were under repetive strain for several years by what I now think was wrong-headed pt regimen. Dislocated shoulder blade in '83. Was troubled by head pulling to r. esp. in car. In late '83 I had a drug insult to my brain by a wrong-headed Ganlion Block Injection (ordered by neuro #!), and in Spring '84 anathesia was given in minor female surgury. Neuro 2 in Fall'84 dx PD. Had slite tremor & little swing r. arm. No drug treatment. Same N dx PD F'85; 2nd opin. fr. N 3 dx PD. No drug treatment. Continued w/pt & water exercise. Severe Neck Sprain just happened. Mechanical, then manual, traction left me w/periodic jaw tremors & stretched neck. Fr. late '85 to '87 put on Benedryl (caused rash but helped some), then Symmetrel (couldn't stand! affected throat!). Then Elavil, 25 mg at bedtime, helped a lot w/ongoing neck pain & arm tremor. @'87/'88 N 4 (in N 2's office) ordered a trial on Sinemet, 25/100, which I took 3 x's a day, in add. to Elavil. In what I now think was an unfortunate move on my part, instead of going back to N 4 for follow up, I elected to go to Neuro 5 (becuz he was a big honshu in PD research) The only thing was that the lack of continuity in my case and his view of patients through the research window may have worked against me in the long run. Will write Chapter II at a later sitting. Barb Blake Krebs [log in to unmask]
