I have had P.D. for 4 years. I'm on sinemet, Azilect, and Mirapex. I have been doing fairly good except for my balance. I use a cane. A few days ago, I had some very strange happenings. 1. I noticed that my vision was really blurry. I went to the Opthalamologist (SP) and found out that my vision was really down. He kept me there for about three hours doing tests and the longer I was there the better it got. by the time I left, everything was fine! 2. the next morning I was getting out of bed and almost fell to the floor. I had no strength in my legs at all. Could not get up out of a chair all day and felt like I could barely walk. My knees were incredibly sore. I have never had that happen before. by the next day, I was much better. My knees are still hurting and feel a little weak, but much better comparatively speaking. Has anyone ever had this happen before? Would the weakness in the legs be "wearing off" that I have heard about, but never had? Any thought would be appreciated!
