I have had Parkinsons for about 4 years and my symptoms are considered to be mild, I think, at this point. I have noticed that a lot of times recently, I wake up and I am biting down really hard. I have some caps in the front and they actually seem sore. I don't know if I am grinding my teeth or not. Has anyone else had this problem? I have also awakened myself with my arms being up in the air. Is this a symptom also? And my last question is within the last few days, I have felt really off balance and shaky. Is the past, my symptons gradually got worse. However, this last weekend, suddenly I was off balance and my hands were shaking and today it seems to be worse. Is this the way this works?
