I had a painful carotid ultrasound today. They aren't supposed to hurt but this caused pressure and pain in my ear, my teeth, and the side of my neck plus the back of my head hurt. For a little while there was mild tingling inside my cheek. I called the doc - his assistant said that they had never heard of anyone complain before. I've had other ultrasounds before but they didn't hurt. Something must have gone wrong - anyway, no one is talking so far.
