the one on the back is a pain because I usually nick it to one extent or another, last time I got it real good,, so recently I have been putting my finger on it and shaving to it. The one on top is no biggie.

I recently had a bump removed. I also used to put my finger on it when shaving. My dermatologist removed it by Laser and two days later I could shave my head- a little cautious - as before resp. much better without fears of nicking and cutting the bump.
