I take no meds so the pain is not related to meds. Not a steady pain, just often throughout the day. So painful at times I cannot walk or get in the car. I Searched "hip" on this site. It is somewhat common ache. I have appointment with ortho doc this Friday to discover if there is another cause other than PD. My wife and I are not expecting the ortho doc to know much about PD but maybe he will surprise. I will post an update.
