I have recently found myofacial release therapy, via physical therapy, for pain (from fibromyalgia, which can also accompany PD, although I don't have PD-my husband does). It is a God-send and very helpful. The treatment helps to release tension on the hurting muscles while building up the "smaller" muscle to help balance the load (over-simplified layman's language, but that's the idea). Take to your doctor about prescribing some physical (or even occupational) therapy for you. It makes you feel good enough to exercise on your own. When those endorfins are release, it seems to help everything! Another plus: most insurance pays heavily for rehab and it's so helpful!
