HI, My husband seems to have maybe a virus??? He has hot and cold chills, body aches, head aches, It is the 4th time in 3 months it has hit him. Had it last 2 weeks ago and went to an out patients at hospital, had his blood pressure and temp checked. His temp was 37 and his blood pressure was fine, was told to go home and rest and have plenty of vit c. After about 3 days it went away but today at work he is complaining of body aches again. why is this re occurring.
