About 10 months ago I started experiencing extreme muscle fatigue and soreness in my legs, whenever I would walk on my treadmill my legs would cramp severely then basically give out, but along the course of the 10 months the muscle soreness has begun to spread all over my body. Different muscle groups from my forehead to my feet now randomly spasm and cramp. I m also beginning to have extreme burning and tingling at the base of my neck and numbness in my hands and feet. The muscles in my arms and legs will lock to the point that I need help to move them. I ve also begun getting very confused to the point that I forget who I am and where I am and it seem like everything is getting worst. I just need help trying to understand what is happening to me!!!
