I think it is a universal problem until you get those fingertips toughened up. One thing I've found that has helped me is using GHS medium Silk n' Steel guitar strings. They are a little easier on the fingertips and the mediums give good sound, stay in tune well, and last a long time. The GHS brand was given to me by a professional musician and they are reasonably priced too. I hope this helps...have a wonderful day and keep practicing......
