I have recently had gastroenteritis. I have felt that my inguinal and abdominal lymph nodes have been enlarged. There is no pain associated with any of the lymphadenopathy. I also have felt a left supraclavicular node enlargement, again it is not painful.I only feel a single node enlarge and I am guessing it is because it is because my body is responding to the virus. I am assuming this all has to do with my gastroenteritis (stomach flu). Could this just be because my supraclavicular node is draining my abdomen?Is there any reason to be concerned? Thanks so much!
