for others it's the COMBO's of some of your meds, epinepherine AND your condition.
I do know that MS folks are far more aware of these interactions than most people are tho...I don't know all the hows or whys of it all? I just know that most circumstances have been well documented [and...I'd learned this all over 5 years ago?].
Only thing to do for now? Is to find out what 'good stuff' they used? Then try to avoid it in the future....there likely is other 'good stuff' available that can work as well yet not add to problems. Tho some of the anathetics my dentist uses now are shorter lasting..but? They have to work more quickly, so... I'm not sitting in that chair soo long! Plusses and minuses to each and every thing, I guess.
Especially important IF you've autonomic issues to NOT aggravate them any more than possible. Bad enuf as it is! NO?
Good luck! 's !! - j
