from now on dont drink alcohol
Sorry you are having these symptoms. Usually, lymph nodes are not painful when you have lymphoma. But one sign of lymphoma that is rare is painful lymph nodes after alcohol consumption. This usually happens within minutes of consuming alcohol. So normally the lymph nodes would be swollen and not painful but then they become painful when you drink alcohol. I don't think the alcohol makes them swell from nothing to a large lump but it might make them get bigger than they are already. Other signs are fatigue, night sweats, fever, unexplained weight loss, back pain, liver and/or spleen enlargement and bleeding easily. I guess it would be best to see your hematologist or other doctor. I hope it is a virus or something else.
i think you should drink a lot of water and get more sleep, but make sure you consult with ur Doc
