John, my guess is that the blisters are merely that and that they'll go away with time. I won't guess about how long because like everything else, healing is an individual thing.

As far as the shaving thing, yeah, an electric might be the way to go. I just plain didn't shave from a few days before my neck dissection until at least 6 months after RT. Wasn't worth the bother with all the numbness in my neck and cheek. Then I dutifully shaved for a year or so until I decided it was too much trouble. But I had a beard for many years in my 30s and 40s so it's a natural feel for me.

Hang in there buddy!
