7/24/00 I was diagnosed with ST. Is there anyone out there with this condition who was previously athletic before the onset of ST? Several years ago I was a body builder then switched to marathon running. Since my symptoms began in May,00 I can barley run more than acouple of miles without extreme fatique and or ST symptoms coming on. I've tried lifting again but neck muscles tighten and the spasms begin. Is anyone out there with ST able to run long distances without problems or any suggestions on exercises. Help,I'm gaining weight!
