Hello,
Thanks for posting your query,
The location of your pain is indicitive of a few things. Of course, ear infections can cause this type of pain...pain that feels like it is in the
ear canal, behind the ear, jaw, etc. An outer ear infection is a likely cause. You don't actually have to be a swimmer to have swimmer's ear. Any moisture left in the ear can cause this (such as a shower or bath). Also, you didn't mention if you have had your wisdom teeth removed or not, but this can cause
jaw pain and pain behind the ear that will feel as though it is radiating. There is also a condition called
Mastoiditis. This is an infection of the bone behind the ear, or from an
enlarged lymph node. Mastoiditis is a bacterial infection of the mastoid air cells (small, air-filled cavities located in the
mastoid process, which is the bulge in the skull behind the ear). This is something you will definitely need to see your Dr about.
I hope this information has been both informative and helpful
Regards
