Question:
Has anyone tried this...and if so how does it work?

Answer:
my doc gave me some, it was the kind they use for women when giving birth, so it numbs it up quite a bit.

worked great, the blisters even went away before i had expected them to.

Answer:
I use aloe vera with lidocaine in it. It helps alot relieve the pain but only last for so long. They have aloe in a spray bottle now so i was thinking that that would be more convient, for say when im out and about.

Answer:
so do i put it right on the blisters?...and how....also does it sting when i apply it? .....can it go on inner or outer sores?

Answer:
the one i have you put directly on the sore. and it can go inner/outter.
i wouldnt rec. putting it all the way up there for "internal" sores, as the numbing feeling might irritate you more but its fine to use on the inside of the lips etc.
