Hi Doctor, over 2 months ago I started having serious anxiety and panic attacks, which caused my neck to stiffen up. I ended up becoming so health conscious over my health as a result of the anxiety and started stupidly scanning my entire body for lymph nodes, and found a small (1 cm sized) movable one in the left supraclavicular fossa, this freaked me out so much (However, I do remember getting a vaccination 4 years ago which caused this area to swell at the time). I then came down with a sinus infection and began to have aches in both my left and right supraclavicular fossa (Maybe from the constant poking and prodding or maybe from the stiff neck and anxiety). I have also been lifting heavy weights at the gym which can make the area hurt sometimes or become stiff and uncomfortable. I used to experience shooting pains down the left side of my neck around 5 years ago (but do not get this anymore). And I have always got aches in my left clavicle my entire life when lying in odd positions for too long. I have found that the aches are worse in my left side now, but will start to feel better after a few days. Then I ll sleep with a low pillow and wake up with the aches again. (Which is making me think it could be a strain of some sort). Just to be safe, I visited a doctor who felt my neck and said she feels nothing to be concerned about. And also got a second opinion from a specialist in Ear, Nose and Throat who really dug around in my neck and said the palpable lymph node is nothing to be worried about. I m wondering what you think these aches could be on my left supraclavicular fossa? And how they could be treated? (I should mention, it also sometimes radiates an ache into my traps and upper pectoral.) I think it may be muscular, a tendon injury or ligament. As I may be susceptible to tendon injuries as my groin is very weak (Hurts after every game of football I play) and I once suffered from a 6 month hip tendon injury. Also as the aches only really started after I suffered anxiety attacks. Maybe useful to know, I also suffer from post nasal drip and tonsil stones. (Which the ENT told me is not a big deal, and said the tonsils themselves look healthy enough, and that I could have them out if I wanted, but did not say it was by any means necessary) Sorry for the long question, just figured it would help if you knew it all!
