Hi again .....
Any doctor (even your PCP) can order an MRI with contrast, which is the most definitive way to determine the presence of neuromas or tumors of any kind. The Tesla 3 MRI machine is more powerful and can take smaller slices, which theoretically will pick up very small growths.
If I were you, I would contact the physician with whom you have the most confidence and he/she can order the appropriate MRI with contrast (usually gadolinium) if you explain all of your symptoms to him/her. Then, when you have the report, it will be time to seek the best specialist you can find to determine appropriate treatment for whatever it is. If it turns out to be an acoustic neuroma (aka vestibular schwannoma), the anausa.org has wonderful resources to guide you in the decision-making process.
Let us know what you find out.
Thoughts and prayers.
