Sloth,

I am not familiar with MAC.

Are you talking about a local injection to numb just the area necessary or a general to make you sleepy but not but you out?

I have had just a local anesthia and also a general where I have been out. I have never had a problem with my MS at these times however, I do deal with more fatigue than usual.

I would recommend you talk to the anesthsiaologist about your MS. Any doctor I deal with no matter what I always let them know I have MS
