For the past few months I have been feeling extremely fatigued. I've been getting bruises and one time I got a gigantic rash that covered my whole body and it seemed to come out of nowhere. I have no appetite, I wake up at nights sweating profusely and my tonsils are swollen. Sometimes I go through periods where I get this intense pain feeling like it's coming from within my bones. I suspect that I may have leukemia and I was thinking about going to get it checked out, but the thing is tha I don't have petechiae and I hear that this is a big sign? I don't even know how to bring it up with my doctor.
