Is pain in lymph nodes (of neck) after drinking alcohol a strong sign of hodgkin's? No major sweats/weight loss but regular fatigue /few small swellig

See your doctor. Fatigue, lymph node enlargement and associated pain after drinking alcohol warrant further investigation . Other symptoms like fever , weight loss or night sweats are called b-symptoms and they don't necessarily have to be present. Another classic sign of hidgkin's lymphoma is itchy skin after consuming alcohol. Please dont wait and see a doctor.
Not likely. Painful lymph nodes is almost never a sign of hodgkins lymphoma, especially without any weight loss or night sweats. However, i agree with dr. Kittaneh, your should definitely get it checked out.
