Fingertips burning

Hi,

I have been using iPhone and iPad for years now but in the last two years I have had extremely sore and burning sensation in my fingers from using the touch screen. I just purchased a new iPad and iPen to limit my use of the touch feature because I have not been able to find any solutions to this problem. In posts throughout the net I have read of people describing the exacts same issues but have not seen any suggestions for why this has happened or any remedies for the curse. Would appreciate some constructive input.
