Hi, my husband (50) thought he had a cold, was sneezing - chest is clear and he was given anti-biotics as thought it could be turning. Now he is sweating, at times it is pouring off him, but is feeling cold. His skin is scorching to touch but temp of 37.8. His muscles are not just aching - he is in pain with them and feels it's his bones also. He also has a vit D deficiency-tablets prescribed. Please advise.
