Hi Anthony,
No not a stupid question at all While hearing loss can occur in MS, it's considered more common to have it associated with some other issue. I don't know if this will help, but I get yearly hearing exams and some questions they ask me are: are you asking people to repeat themselves? turning up the volume on the tv/radio? any buzzing or ringing?
My husband doesn't have hearing loss exactly. He can hear a one on one conversation just fine, but in a group setting with a lot of people talking he has trouble hearing anything specific. His neuro explained it as background noise and having problems processing too much info at once.
I hope it gets better for you.
Kimber
