Re: Intense, sharp earache
Look up bruxism; check into a mouth guard (inexpensive ones can be had at drugstores).
Hold off on expensive procedures like MRIs, CATs until you've been checked for other things that don't require imaging diagnostics. That over-use of imaging procedures is one reason why healthcare is so darned expensive now!
Also, the facial nerves can indeed mimic earaches, particularly the seventh cranial nerve where it enters the skull at the pons. Perhaps check with a neurologist as well for nerve conduction studies. If you have a history of chickenpox, intermittent swelling can cause nerve pain. The chickenpox virus likes to hide out dormant in nerves.
