Well, that ENT retired recently, so he won’t be promoting drug resistance any longer—again, assuming my impression was correct that he was saying he would have prescribed the other drops first.
Sorry for the slight against all docs-in-the-boxes.
All this happened just before the Covid lockdown, and then the ENT retired. I didn’t have a chance to see him for a follow up. The hearing loss, which is extremely slight—just enough to be noticeable—hasn’t changed in all this time, but if there is a chance it could be restored I’d gladly see another ENT.
