you had posted before, that you play only for 2 months - pain in fingers is normal when you play for such a short time. if you are looking for a little bit less hard strings you can buy nickel ones. but i don't know if it helps you, because you didn't write which hand's fingers hurt you. if it's left hand, maybe you can think about lowering the strings. but the only way to forget about any pain is to play much and create a "shell" on your fingers

practise, practise, practise!
