Dear Patricia Yothers, Edwin P., & Bev S. I alslo experienced my first symptoms of PD after surgery: a biopsy on lymph glands above the clavicle. Numerous doctors attributed the subsequent tremor, pain, and stiffness in my lefy hand to damage done during the probing near my thorasic outlet. The original lymph swelling cited as the reason for the biopsy was caused by steroids given for "arthritis" which turned out to be a bone spur on my shoulder. All of this delayed diagnosis of PD for almost two years. Subsequent surgeries for the spur and three other unrelated problems meant more painkillers before the meperidine danger was discovered; I'm declining any more more repairs! A recent sciatic attack, October 95, sent me to the emergency room with all medications in hand, including Eldepryl. I hadn't heard about the possible interaction between Demerol and Elderpryl, and neither had the emergency room doctor. I was given a shot of Demerol and a follow-up prescription for the same. I was lucky and suffered no reaction. Now I'll know better. Thanks PD information exchange--no telling how many lives you safeguarded. I am 60, 1.5 years diagnosed, taking Eldepryl 5 MG x 2 per day, and now wondering and worrying about that since the UK study. Kathy K.
