I had that experience one year ago. There was no pain during the mohs, just emotions. Wondering how big of a hole you would end up with, and how the repairs will look. I had an advanced BCC on the side of my nose and the mohs left a hole that could fit a marble. There was hardly any pain afterwards, as I was to wait 5 days before my surgery to repair it. They took some skin and fat from my lower neck area to fill it in. It looked awful at first, but quickly improved. Again, no pain to speak of. The round, lighter colored patch is not noticeable with make up.
