Misha, you absolutely must make a tradeoff decision that favors your speech comprehension and ability to discriminate speech and understanding in day-to-day life! No kidding, I limped along with a wonky aid in one ear, thinking my other ear’s aid would tie me over? Big mistake. I dropped from 80% word comprehension to about 50 (at the same db) within 1.5 years. The brain/ear connection is VITAL - even more so, cuz aids do not fix the problem, they merely help us (and our brains) compensate for the hearing loss and do the best job of interpretation.
It is puzzling how vague and seemingly unhelpful your ENT is! GO to another one. If the condition is “hereditary” examine your family tree: IS IT? If not, you got a line of BS. Main point is, whether hereditary or not, getting worse or not, you have to make your hearing (and quality living) priority #1. Other things can be postponed to save money for this. Hearing is critical! You can’t even drive, walk, work out safely at the gym, or be truly independent unless you have confidence in hearing. Good luck getting this resolved.
