Just a thought on Parkinson's this morning...with what I think is arthritis. I've already had experienced terrible cramping of the toes which helps you not to walk. I take my pills but found out just a plain asprin helped the cramping. I plan to ask my doctor for a high powered asprin when I go in next time. I plan to stay out of a wheel chair...if I can. Sue.
