I am hoping someone can answer me, sooner the better. I am a 37 year old female who has been having severe fatigue, unexplained weight loss, depression, fevers daily, sometimes over 102 at night for weeks,night sweats, extreme weakness, loss of apetite and body aches, I went to doctor, had a WBC of 20,000 and then was sent for a Peripheral Smear Blood Test last week, I feel like I am getting sicker by the day, but have no flu symptoms like sore throat or cold symptoms, what would my doctor be testing for?
