Doodlette .....
Welcome to this Forum. Yes, your symptoms are seemingly consistent with an AN, but there can always be other reasons so try to relax until you have the results from the MRI. You mentioned you do not know if the MRI is with contrast or not ..... call and check before you go and insist that the order be written with contrast or the MRI is quite meaningless for diagnosing an AN.
The reason for ordering an MRI when going to the doctor for hearing loss is because you have single-sided hearing loss ..... a big tip-off for ANs. I would not pay for a hearing aid until after the results from the MRI. If it is an AN, whatever treatment you choose will very likely change the degree of your hearing loss. I had 80% hearing (20% loss) in my AN ear, 100% in the non-AN ear. Post surgery I have 20% (80% loss) in my AN ear. However, with a high-end digital hearing aid it has been a huge improvement and I have no problems hearing in one on one situations. Still have problems in a noisy environment, e.g. restaurants, large crowds, outdoors.
Best thoughts and let us know how you are doing.
