Every time my mother feeds, she gets sick ...

Every time my mother feeds on her anterior ear muscle, it swells and she starts to feel sick. Her hands and feet tingle, her eyes turn red from dysentery, and she vomits. We have already been to several specialist plus they have not discovered anything about it. What could it be?
Expert answer:

The fact that "swelling the muscle" is associated with chewing should mean that it is a question of positioning the teeth and jaw, in which case the ideal would be to look for a dentist rather than a doctor, all other symptoms you have described should be related to emotional problems.
