Ouch, Cramps like I have never experienced from the waist down. My head in under water, far under. I am sweating and cold. I have a fever. Upset stomach. Aches. Heavy limbs. Have seen the doc 3 times. Flu like head. Can't think straight. Hadn't sleept right for 4 nights then slept 14 hours. Slept again today, will go back to bed now. YUCK.
