About a year ago, I yawned and got this awful pain in my neck (front/left side). Since then, this has happened to me about 4-5 times, the most recent being last Friday. When it happens, it feels like a cramp and if I swallow a few time, the pain will go away. But, for several days afterward, my neck is very, very sore in that area and it s hard/kind of painful to swallow. I live in constant fear it s going to happen again. I ve been to an endocronologist (am currently taking medication for hyperthroid), an ENT, my dentist, my GP. I ve had an ultrasound, an MRI ... nobody can diagnose my problem.
