My pulsatile tinnitus is getting worse especially at night. Went to ENT, he did not find anything. So now neurologist who has found a pinched neck nerve and is concentrating on getting rid of that. But when I was in the ER for what i thought was a possible stroke they did an MRI that found my right external carotid artery clogged at 'greater than 50%'. Neuro is completely unconcerned about this, states 'we don't do anything til its around 90%' (?!). Put me on some physical therapy and possible cortisone shot for the pinched nerve, which bothers me as well, it is true. I just don't like the way she has brushed aside this carotid artery thing, first she said I needed to follow up with the 'people who did the MRI'. I said, um emergency department, they said do followup with you guys. Just completely unconcerned about it. Is pulsatile tinnitus not something a neurologist does and if not them, then who after the ENT found nothing?
