I was stretching and yawned with my head turned slightly to the left. During the yawn, there was a very loud pop in my throat, just above and to the left of my adams apple. It was instantly followed by nausea and the feeling that I was going to pass out. I felt pain from my right ear down to almost my chest. The right side of my face swelled up. I now have pain when swallowing and can feel the pain in my ear every time I swallow as well. I've been to my doctor, had a CT scan done on my neck, along with a carotid ultrasound. Blood work came back perfect, so my Dr is stumped.
