I have a headache behind my eyes, my eye hurt, muscles are sore off and on and I have hot and cold flashes. My cold flashes make me shiver and teeth chatter and my hot flashes make my whole body sweat. I just had a baby and am really sleep deprived, I dont know if that is whats causinh my sickness, but I just want to know whhat is wrong with me and how to fix it?
