For the past month I've been having recurring fevers (102F & 103F) and night sweat. Each time I experience accompanying symptons such as chillness, muscle/bone pain (neck, shoulder, arms, legs), mild headache, and in general just feel tired. I don't have other flu/cold symptions (no running nose, no sore throat, no coughing). I've had 3 occurancs in the past month. Can anyone tell me what are the possible causes and any tests I should do? Thanks.
