Hello, I am 18 and have had a large (about 1.25 in.) hard lymph node under my right ear, behind the jaw for about 1.5 months now, it has not changed in size as far as I can tell and is not tender or painful. Additionally, I have had a slightly swollen right tonsil and a sore throat with slight cough for the past two weeks. I have had no other flu-like symptoms; no fatigue, fever, runny nose, etc. I was wondering if the sore throat and cough could be caused by the acid reflux I have been having lately do to stress and the tonsil could be caused by my first wisdom tooth recently breaking through the skin? I have no idea what to think of the lymph node though...
