This just started recently.
It would sound like my hearing would dull just slightly and I would hear a high pitched noise of some kind. Not like real painful but it was uncomfortable and it would have like every 2 minutes.
It went on for like 2 or 3 days until it stopped. Since then I have had a moderate headache and pain meds aren't helping.
My boyfriend plays in a band and sometimes I go with him to practice and get stuck sitting behind his amp. I don't know if that's what could of caused the noise or if something else has.
