Have any of you had experience with physical therapy? Is it helpful?

I saw a physical therapist in the hospital, who gave me some exercises and suggested I find a PT who specializes in neurological problems.

My thinking is that any exercising I do will use up what strength I have, and make me worse and not better; but perhaps it would make me better in the long run? It's not going to do anything to enhance nerve-muscle communication, but if I had stronger muscles, maybe I could get more out of the communication that's there? I just don't know.
