I have been on pramipexole 3x day for a long time. Recently had cervical surgery and midway thru recovery, I began to experience serious balance problems. Use to play a lot of tennis, but now am reluctant to play, until I resolve the balance problem. In reading over the many comments here, and after some medical tests, it looks like it could be a pramipexole problem. This is both encouraging, to know the cause and discouraging, knowing I can not fix it without having my RLS come roaring back. Not playing tennis, has led to weight gain, which as yet, I have been unable to reverse.
I have found that regular stretching helps control the RLS. It does not eliminate it, but when I am having trouble, stretching reduces and sometimes eliminates the immediate problem, for awhile. I hope this can help others as it does me.
