I've had these lumps on my both collarbones sine April of this year. they do get painful at times. I had blood work done everything came back normal. I do get night sweats on some nights, I do get itchy on occasions , no fever, very fatigue all the time. my appetite is up and down. My doctor has no clue to what is wrong with me he said I'm a mystery. I don't know what to do.... I need answers, this is driving me crazy.
