So I have been complaining to my dr for nearly 2 yrs. I have a swelling on the left side of my neck which gradually seems to be getting worse and more painfull. I am now getting painunder my left arm and almost into armpit.  I have had an mri scan and camera up my nose to check throat and been told nothing wrong. I feel rubbish alot of the time. WHat can anyone advise. Dont seem to be getting any further help from GP.
