Are you able to tolerate Benadryl? Maybe liquid Benadryl so you can take a little bit at a time. Benadryl is relatively contraindicated in MG but some people can tolerate it in small doses.

It appears as if you are having a more serious allergic reaction. Any hives? If it were me, I already would've gone to an urgent care center or my primary doctor. Your neuro tomorrow will be completely at a loss, since he's a neuro and doesn't sound very effective.

You need some kind of advice right away, okay? And in person.
