bsf1968,
If it was the pad of the finger that you skinned, unfortunately, it will take quite a while.
There are a lot of nerve endings in the pads of the fingers. When you took the skin off, you basically exposed those nerve endings. Scar tissue is not a very good substitute for the real thing, but, it will, with time become tough.
Just like when you first start playing the guitar, you had to build up the calluses on the pads of the fingers, so they didn't bother you, you will have to toughen up the scar tissue on the pad of that finger.
It will eventually toughen up, but it is going to take quite a while.
Good luck.
