For the last week my legs have been cramping mostly in my thighs above my knees. Kinda feels like I just ran a marathon and my muscles are just very fatigued. It got a little better a day ago and today I have been in so much pain from it. I'm now cramping in my lower abdomen along with both of my legs- hips down. Nothing helps whatsoever. I'm going to call my doctor tomorrow but I wanted to ask if this has ever happened to anyone else..

FYI: I'm not dehydrated and I haven't done anything out of the ordinary activity wise.
