I think I have eczema?

Hey everyone so recently about 2 days ago I noticed a little cut in my finger it didn’t really bother me and thought I had cut my hand on something but as these past 2-3 days have progressed the joint at which ur fingers flex on each hand and finger have little cuts/splits in the skin my finger tips have become increasingly dry and gritty and my fingers and palms have become dry itchy and flaky I’m not really sure what to do I’ve tried using lotion frequently throughout the day to keep my hands hydrated but they only stay smooth for a couple minutes then go back to being dry flaky and painful please help lol.
