Ear Hurts from a Cough-Pressure Injury?

[Ghostkitten666]

I hate coughing because every time I get a T spike from the noise. So I decided to cough into a blanket. Pretty harmless, right? Just an average cough from a tickle in my throat (not sick).

Well at some point during the coughing I suddenly felt my eardrum bulge out! Now my ear is in pain and my hearing is not so great. Got a sparkler kind of T going on as well.

Went to ENT a week ago so there is no infection, nothing going on except for a bit of ETD not connected to infection. So there is no fluid in my middle ear.

Um, help?
