Everytime post having meal there is a small hump appeares on the top right side of the throat and just below the jaw /ramus bone of my wife.  Circumference of this would be 2 inches approx. It happens every time post she finishes her meal and last for an hour and then gets disappeared at its own. It dose not create any pain. It's been an year now. We checked with a Dr earlier but didn't find any solution. She takes thyronom 25mg every day. What could be the problem? Should we consult an Onco? Pl suggest
