My wife had a low grade fever for about two weeks which is now gone. Body aches which have now subsided. But she still has a mild sore throat and today has started to have some pain in th e jaw. She is extremely fatigued. She has been to our family doctor who did a full blood workup and urinalisis and other checks. All tests came back normal. She has been feeling ill for more than three weeks, but the doctor can find no aparent reason. He has put her on antibiotics just in case she does have some type of bacterial rather than viral infection, but other than giving her diarreah, the antibiotics have had no effect. We also checked her for a tick bite for the posdibility of lyme disease, but found nothing. Any guesses what this could be?
