Hi, have this chill and dry cough for the past three weeks. Three weeks ago my abdominal muscles was killing me. Last week my right upper chest muscle was stained. I had seen my doctor twice in the past three weeks. My doctor told me it s all muscle strain. It is due to my over-exercise. Today all my muscle pain are gone but I am still getting the chill, cough and night sweat. Over the past 3 weeks I will wake up in the middle of the night to change my cloth and bed sheets. I sweated that bad. The last time this occur was 2 days ago. I am thinking I have some type of internal infection. I also have a tooth that need to be remove for implant. I am schedule to do so in a couple of weeks but it s hard to visit an oral surgeon when you are coughing. Can my tooth be the of my fever like symptoms? I am in my mid 50, male, non-smoker and non-drinker, and healthly. I exercise extremely often. Please advise
