Hi Doctor, I am a 20 years old male. I have an enlarged submandibular node for more than 1 year, it feels rubbery and movable and its about 1.5cm. I went to an ENT he told me that there is nothing to worry about. He told me that I have sensitive nose and probably the inflammation cause the lymph node to swell. Also the chest x-ray did not reveal any mass. However, recently I have been experiencing some itch, chest tightness (especially when I take a deep breath) and some weird feeling at my armpit. I am worried that I have lymphoma.
