Yeah man, this is completely normal. Your fingers will become sore especially if you are just beginning, cause your fingers are still really tender and rubbing them across the strings when you’re playing is irritating them. It’s sort of feels like you cut yourself on the strings. I would not worry about this, cause your fingers will eventually build callists to protect them. If it becomes too painful, stop playing for the rest of the day; just resume the next day, and if you play regularly, this pain should subside within 2-4 days.
