Dear Patricia Yothers, Edwin P., & Bev S. I also experienced my first symptoms of PD after surgery: a biopsy on lymph glands above my clavicle. Numerous doctors attributed the subsequent tremor, pain, and stiffness in my left hand to damage done during the probing near my thoracic 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. This delayed diagnosis of PD for almost 2 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 repairs! A recent sciatic attack sent me to the emergency room with all medications in hand, including Eldepryl. I hadn't heard about the possible reaction between Demerol and Eldepryl, and neither had the emergency room Doctor. I was given a shot of Demerol and a follow-up prescription for 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 x2 per day, and now wondering and worrying about that since the UK study. Kathy K.
