I had temporary hearing loss in both ears due to the loud sounds of what I can only describe as ocean sounds. It was crazy. Had terrible pressure and vertigo, as well. This was a day after the first injections. I went to urgent care, sure I must have a sinus or ear infection. They said other than some slight inflammation there was nothing.
It took weeks to wear off.
I went ahead with the second months injections and it wasn’t nearly as bad but did have some lesser hearing issues with vertigo and continued pressure. It finally wore away and I’ve never had another injection since. Dr tried to tell me I may have Ménière’s disease however since stopping the Evenity I’ve not had any of those issues.
