Hello and welcome to Health care magic,
I am Dr Sriram nathan, an ENT surgeon and i shall try to help you out with your problems.
You seem to be having a problem with the joint between the ear and the mouth which we call the TEMPOROMANDIBULAR JOINT ARTHRITIS
Like any other arthritis, even this condition requires rest to the joint and pain killers like paractemol in consultation with your doctor.
You should avoid chewing anything solid or hard for the next two weeks or so
You should also avoid making big movements of the jaw such as yawning or streching it too wide open.
Do these for a week or so and if you do not get better then you must consult and ENT surgeon and also a dentist
who can suggest a more directed treatment
take care and get well soon
Dr Sriram nathan
