Anyone experienced dizziness or optical changes with exemastane

Hello
I’ve tried letrozole, anastrozole with terrible side effects. Now on exemastane for 4 weeks. I’m experiencing much dizziness and found out at my annual eye dr spot that my optic nerves are damaged. Anyone else have this side effect?
The letrozole damaged my ulner nerves in 3 weeks causing me to have bilateral cubital/carpel tunnel surgery. The anastrozole made my brain fog so bad I couldn’t function. Im trying this 3rd AI and why would it be different lol. I’m fighting!
Blessings to all!
