Not sure offhand how long this has been lasting, but I am always fatigued for some reason. It does not matter if I sleep 3 hours or 12. I wake up still tired and with morning stiffness and occassional muscle pain. I also have stomach pains followed by diarrhea every now and then. As for physical activity, that also plays a factor. I bowl a few times a week and am usually fine as long as I don't bowl on back to back days. When I play basketball, football, or something that is pretty physically demanding, I am sore and at times, in pain. The last couple of times I played basketball, it lasted for 3-4 days. My mom has fibromyalgia and I have heard that the two are often related. I am not sure if it is genetic or not. According to what I've read, my symptoms apply to Chronic Fatigue Syndrome and also partially to MS. I am in the process of moving and need to move my medical files to another doctor's office. Honestly, this scares me because my symptoms apply to 2 serious conditions. Has anyone else had similar symtoms? If so, how did it turn out? For the record, I'm 21
