Why Do I Have Painful Fingers When Am Playing Guitar?

I Think New beginner always have painful fingers when the are playing or after the session. Unless the have iron fingers.
But when the time goes the will be use to it and on it will should be fine.

If you're going to be doing any rigorous playing or anything of that nature, warm your fingers up first. Do some good stretches; make sure to get the blood flowing' there.

Learning guitar, it’s a gradual process, just learn a little bit at a time and enjoy yourself.
