I've had this illness for a little over a year with most of the usual symptoms that come and go unpredictably. My most disabling symptom is a sense of heaviness and weakness in the legs. Last fall this got to the point that I began to use two forearm crutches to help me walk. I've noticed though that the last two weeks, since the weather has started to warm up, I can walk much farther without my crutches, though I still use them for long distances such as the mall. Has anyone else noticed a connection between weather and weakness or difficulty walking?
