Not sure if that could cause painful lymph nodes
. I’m kind of worried about having a cancer
or leukemia. I have done a full blood test (CBC) that came back normal. I’m just wondering if these are all throat infection why is my CBC blood test normal all the time and the strep throat comes back negative? Mono is negative as well. And the sore throat is usually deep down inside my throat near the thyroid. (did a thyroid test that was normal too). Could this be something serious? I'm 20, male.
