I'm starting to get nervous, just wondered if anyone had experienced anything similar. I noticed a throbbing pain above my collarbone on my right side about 2 weeks ago. It seems to come and go and gets worse when my heart is beating faster (like when i'm nervous). This happened a couple days before my Wife was diagnosed with an upper respiritory viral infection. About 5-7 days later I came down with a severe sore throat and lots of sinus drainage and lots of chest phlegm (croopie). I went to the doctor last Tuesday and got on a 5 day supply of antibotics for a sinus infection (Z-Pack). Felt better for about 3 days, then woke up Saturday feeling like I had a brand new sinus infection, still persistent coughing. Today I am starting to feel better, still a cough and on the tail end of my sinus infection. But still feeling a small kinda sharp/dull pain in right side of neck above collar bone, but almost feels likes its deep in there where I can't feel it. Pain almost could be described as feeling like a cramp. I have been feeling around kinda near the pain and I can feel a small almost bean shaped node which could be my Supraclavicular lymph node? I can move it around side to side and seems to be right near the pain. I don't know if it is truly "swollen" so to speak. From what I am reading online everyone that is describing there swollen lymph nodes are saying they are golf ball shaped. I have been googling these symptoms for the past few days which I hate to do cause it always makes you fear the worst but I keep finding "Supraclavicular lymphadenopathy" which it says is very bad. Everything I have been reading says that if pain is there and you have a upper respiratory infection you probably have nothing to worry about. I am 27 and in great shape. I'm wondering if this could be mono or something. Should I just sit tight for the next 1-2 weeks and hope that pain and possible swelling goes away?
