I worry that some day some doctor is going to tell me I must have an MRI. It could be a matter of life or death. In that case I will buy foam ear plugs, insert and make sure they are fully open then put on regulation ear muffs that the hospital has approved for MRI use, and tell the radiologist or whoever is administering the MRI not to play any music through the ear muffs and realize that with the foam earplugs I won’t be able to hear their voice so to keep quiet.I am sorry you are in a bad place right now but in my experience tinnitus tends to have bad an somewhat better periods. Hyperacusis can also be improved over time.
