On April 28th2021 patient could not hear. She was deaf in right ear and the day before on April 27 it was like she woke up with pressure in both ears. It sounded like hell like she was in the airplane and by yawning she could not relieve the pressure and went to the doctor and was under treatment with steroids and antivirals and still deaf in right ear." She confirmed pressure is gone, but still deaf and under medical treatment with otolaryngology. She was kind of tossing whether to get the vaccine or not. First went to family doctor to see, didn't think she had an ear infection because no pain and was hoping maybe she would have wax in her ear, but ears were clean and no wax. So they sent her to an ear specialist and they did hearing test and she has pretty severe hearing loss in that ear. So she was still being treated. First the doctor put her on valacyclovir and methylprednisone for about 7 days and then that didn't seem to do anything and now she's getting dexamethasone injections into her middle ear. States she is due for one about lunch time. Pressure in both ears: patient reported has subsided, but then confirms it is a lasting effect comes and goes a little bit. Left ear is pretty much clear but right ear still has pressure and cannot hear and has not subsided. On an unknown date her equilibrium affected and stated has gotten slightly better, minuscule.
