Lenny: Regarding the chest pressure: if all other tests are normal, have your Mom checked for H Pylori. A simple test can tell whether or not she has this nasty bacteria that can cause a wide range of symptoms...from chest pressure, to abdominal pain, to nausea, to ulcers (over 90% of tested ulcer patients had H. Pylori), to MANY other symptoms. If the test is positive, a 3 week course of anti- biotics should take care of it. H Pylori has only been recognized for a few years, and not all doctors test for it. I got lucky, and a doctor that was involved in my treatment suggested we try testing for that right after he said that there was nothing he could find or do for me. The test was positive, I went on the antibiotics, and I got my life back. (BTW, I don't have PD...I'm here for my Dad) Good luck! Sharon
