Those are symptoms of tmj - although I am not certain, its possible that the bulimia stressed the tmj joints - some people experience tmj symptoms merely after seeing their dentist due to keeping their mouths opened wide during cleanings, fillings, examinations, etc. which can also stress the tm joints - located in the temple area above your ears. For some the pain is more below the ears near the lower jaw. Try warm facial compresses in the area several times a day and a soft diet for a few days - if it helps then there's a good chance no permanent damage was done and these symptoms are warning signals that your jaw muscles are being stressed. If it continues you may want to seek help of a tmj specialist so the problem doesn't progress any further. Hope that helps.
