Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that hearing high pitched beeps in ears along with earache and also sensitivity to sounds does not seems to be due to jaw joint problems but it seems to be Tinnitus and can be due to causes like:
-Excess ear wax accumulation.
-Eustachian tube dysfunction
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like Audiometry, x Ray MRI can help in diagnosis and treatment can be done accordingly..
In case if ringing does not resolve then you can be advised medicines like Tricyclic Anti-depressant like Amitryptiline, anti anxiety medication
like Alprazolam, as well as Multivitamin supplements can be advised..
White noise devices can be advised..
You can also be advised Neuromodulation
Avoid exposure to very loud sounds and also avoid diving, swimming etc.
Hope this information helps..
Thanks and regards.
