I wanted to thank all who responded to my question about sudden hip pain, and summarize the replies in case anyone else is interested. It appears that a variety of aches and pains is very common among us, and there seem to be many different probable causes, and remedies. Among the possible causes that were mentioned are stiffness, gait problems, immobility, Restless Leg Syndrome, dyskinesias, postural distortion, compression on the sciatica nerve, muscle stress, and undermedication. Although it is difficult to generalize from one person's experience to another's, the common thread that seems to run through many of these responses is that the primary PD symptons, which make our bodies move (or not move), in very unnatural ways might cause or aggravate these secondary strains, aches, and pain. The suggested remedies included rest, ice packs, heat, physical therapy, regular exercise and stretching, chiropractic, whirlpools, Vitamin B, surgery, or do nothing and see if it gets better on it's own. I've tried rest, heat, and Advil, and the pain subsides, but only temporarily. I'm going to the doctor tomorrow - just hoping he can diagnose and treat this without a lot of tests (though I guess that's not very likely) Thanks again for your replies.
