I have a mass or lump at the base of my neck and for several months I have pain like I ve slept wrong. It has been there over five years, and my Primary Care doctor says its nothing. I was diagnosed with parathyroid about four years ago, but after seeing four Endocrynologist, no correction has been prescribed. After having a Parathyroid Imaging/Sestamibi Scan and recently an Ultra Sound, the last doctor suggest that I see a neck, nose and throat doctor. Help!!!
