It is possible a "neck" adjustment could help along with a switch of strings and "tip" baths to toughen the skin.  The space between the neck and the strings is the "action" of a guitar.  Larger space (due to misadjusted neck or a poorly made instrument) leads to harder pressure to get  the strings to the neck, thus more "sting".   Check at the base of your instruments neck to see if there is a "hex" screw adjusting head.  Take it to a shop  and have them check it.  I like the "Elixer" strings idea also along with the "silk steel" types.   And in the end it after you have tried all the "fixes" it may be you have an instrument with a neck that just doesn't fit your hand, which leads to more "twist" in the wrist, and pressure than necessary.

These are the suggestions given to me when I started.

I started out playing 3 years ago.  I play and amplified acoustic.  There were two tips given to me that helped me get my "guitar fingers" and reduce the sting.   
Tip #1.  Switch to "Silk Steel" strings.  They are about "12" in gauge size and have a different wind, that is easier on the finger tips.  They produce a "warmer" sound than straight nickel- steels.   I now play a Martins 11.5 gauge  to get  a slightly "steel" sound with my guitar, and they are easier on my fingers.
Tip#2.  When you are done practicing.  pour some "rubbing alcohol" in a bowl and rest your fingers in it for 1-2 minutes.  The alcohol, will help reduce the sting, and helps to toughen the tips to form the  calloused area you need.  Even now after a particularly long set, and I have my finger tips conditioned,  I do this. It helps a lot.
