I don't quite get those symptoms, Ian, but I know what you mean. When I'm going 'off ', my shoulder aches and my stomach starts heaving and breathing becomes laboured.
TeeHee, when I was on Ropinirole, I felt like you do. Have you thought about coming off it and trying something else? I guess Levodopa is the next logical step. I find Madopar works really well for me, but doesn't last long enough these days.
Just goes to show that every one of us is affected in different ways. Hate this wretched PD!
