Sensation on scalp after Mohs. How long can I expect to have to deal with this?

I recently had Mohs surgery on my scalp near the hairline requiring stitches and staples. When they removed the staples, there is one area that seems to be more sensitive - when it is touched, I get somewhat of a pain through my whole face/ side of my scalp. They said it was the nerve and would get better 'day by day'. How long can I expect to have to deal with this?
