I noticed one night while putting lotion on my neck the area called the manubrium, which is where the clavicle is attached at the sternum is swollen and bothering me alot.  It feels like someone is poking me in the throat when it gets really swollen.  I have been trying to find out what has been wrong for several months now.  I have seen a Primary Care Doctor who sent me to a ENT who did a CT of my throat and chest and told me I have a hiatal hernia which I already knew.  My Orthopaedic took an X Ray and told me there were no masses and gave me a trigger point injection.  I saw a Rheumotologist who told me it is not rheumotoid arthritis.  Now my Orthopaedic is sending me to see a Shoulder specialist.  I had a reconstructive surgery of my esophogus several years ago and have been diagnosed with herniated discs in my thoracis spine.  I need help because no one seems to know what it is and it is bothering me more and more. Please Help!
