About a year and a half ago, I began having this weird sensation in my throat near my left jaw. It was a tingling, shocking pain sensation. I saw three different doctors and had a normal MRI. I continued to have it for several months. It went away for about 4 or 5 months but has since returned. Now, in addition to this pain by my jaw, I now have a pain in the center of my throat. It is not always there but can occur as a periodic pain and sometimes I have a sharp pain on the same side of my throat. Sometimes this pain goes to my ear. I am concerned I have some sort of cancer.
