What is your history: It could be many things. From a dental standpoint i would be looking at your overall history. Is it tooth related or jaw related? Is it from trauma? After a thorough examination i would contact your physician to find out what his thoughts are and what future tests may need to be run, if any. Hopefully once all of the information is gathered a diagnosis and treatment plan can be presented to you.

See a Dentist ASAP: Hard to diagnose it with that info but since u feel the pain is similar to a toothache, i would start there and let a dentist examine u and take some x-rays. If u have a tooth abscess it could be v. Bad to leave it untreated. If no dental problem found, see an internist md for a medical wkup and possible referral to appropriate specialist. Good luck with this: dentist 1st.
