I was just diagnosed with FMS about 4 months ago. I've been really suffering with really tightened muscles from the calves of my legs radiating into my back muscles, so much so that I feel like if I stand in one spot for just a few minutes, I feel like if I take a step I'm going to fall. I'm taking flexiril, and a low dosage of elavil to help me rest at night. The symptoms have not improved. I do rest some better at night. If anyone knows a way to help this besides what I'm already taking, please let me know.
