I am scared because I have had a swollen lymph node in my neck for over 6 months now. And now I have been having lower back pain. I have pretty much since I can remember had night sweats. I wake up drenched. The doc doesnt think It is lymphoma because my mri just showed a reactive node. I am not sure what it measured though. I wish someone could tell me what was wrong with me. I am about to get married in a week so I am trying not to stress out. The doctor wants to do blood work again, last time about 3 months ago it was pretty normal. It doesnt seem like my node has grown at all in the last couple months, is it common for back pain with this disease?
