For the last years I have had a Mild to Moderate PD. I have been getting by on 25/100 Sinemet 1 a day, 1 MG Mirapex 3 X day and Eldepryl 2 X day. I had heart bypass surgery on Nov 1998. Beginning on March 1999, I started to feel a heavyness in my legs, but I did not pay much attention to that, walking took care of it. Last November, I experienced what I called a Frozen state where I almost keeled over. I talked to my Neurologist who said that I was on a very low dosage of Sinemet, so he upped it to 25/100 twice a day. That has not helped much, I notice that any kind of physical activity gives me the heavy legs. Whereas before walking helped, now it aggravates it. I have read about INTERMITTENT CLAUDICATION, SCIATICA and a host of other possibiities, but I guess my question is: Can this be caused by an acceleration of PD to a different stage? Need your comments, please. thanks, Mario A Gonzalez [log in to unmask] 53/4
