I can no longer straighten one of my legs. I’ve been trying to exercise and stretch, but it doesn’t seem to be helping. It’s painful and uncomfortable when I try to lie flat on my back or stand up straight. Is this because I have Parkinson’s, and if so, what can I do about it?

You’ll need to have your knee examined to understand more about the cause of the pain. To me, it doesn’t sound typical of Parkinson’s. I’d advise you to contact a physiotherapist for an examination of your knee.
