Advice on methysergide

I’d really appreciate some feedback from other people who have heard of/tried methysergide. I have tried about 13 different medications and botox and after 4 years have yet seen no improvement in my migraines/vertigo. My specialist keeps suggesting methysergide but I’m really reluctant to try it because of the side effects I’ve heard about - and because it might not even work I’m not really wanting to take the risk.
Has anyone else been offered methysergide? And if you took it did it help? Has anyone had the bad side effects from it?
I think I’m running out of options and I’m so desperate to get better (as I’m sure all of you are!) that I think I’m just going to have to go for it.

I’d really appreciate some feedback!

Thanks in advance :slight_smile:
