You know, I wonder how much exercise has made a difference for me as well. I was exercising very regularly (running mainly) up until about three months ago, and then I developed a neuroma in my foot...so needless to say that I am not moving much. I can also say that I have felt more symptoms, etc. lately that I had been. I wonder if it is tied to the fact that I can't get out and exercise right now. Hmmmmm...something to ponder.
