My husband has been having severe bouts of fatigue. His arms and legs get very weak , he has begun to have problems walking. He can't walk a straight line anymore, he walks like a drunk but he doesn't drink or smoke. He is 60 years old yesterday, has always been very active and work hard, but is really having a hard time right now. There are times he throws up from taking a hot bath or just no reason. He gets dizzy, arms and legs tingle and gets very weak. We have been to see our family Dr and a Nurologist, they are running every test, but come back with nothing. I saw a show on Television about strange desease and heard about Acute Intermittent Puforia. Could this be what he has?
