I read your question carefully and I understand your concern.
At your age it is indeed very improbable to have MS. However since you don't say much about your history and I don't have the
MRI at my disposal it's hard for me to express an opinion whether it is indeed MS or another issue like blood vessel issues or infection.
Regarding the questions, you should ask him:
- whether further tests are necessary to confirm the diagnosis,
- what is the prognosis for MS when its onset is so late as in your case,
- what are the data on treatment efficacy at your age,
- what about medication safety at your age, higher risk of complications like infections
I hope to have been of help.
