Hi, my husband has been sick for the past 6 weeks with different flu-like symptoms, like a sore throat, fatigue, tight chest, etc. He took antibiotics and finished the course about a week ago. Recently, his chest has become cold to the touch and he feels cold but he also wakes up drenched in sweat. I am concerned. He is seeing his doctor tomorrow but I can't find anything online to explain what a cold chest/stomach could signify.
He is 34, 6'2, 185 lbs and in good health otherwise. Eats well and exercises, although he tends to overwork.
