Why does a dr. insist on parkinson s diagnosis, when all symptoms relate to patient s physical problems? Example; shuffling gait is from no knee cartilage in rt knee, no rt arm swing when walking is due to rotator cuff surgery when 21 yrs old (now 65), and rt arm tremor also from rotator cuff (both since surgery). If a patient did not have these causes of symptoms I could understand a suspicion of parkinson s, but his dogmatic insistence leads me to believe he is either following orders of his drug company patrons, or he is short-sighted (to put it kindly). He prescribed carbadopa, which will lead to parkinson s if I don t have it, and will eventually kill me. Your thoughts, Dr?
