Sorta gross, HELP, not sex related at all

So about a week after thanksgiving my the edges of my lips started cracking horribly like not an unormal amount in general but ridiculous for me. I used Chapstick and I used Aquaphor or whatever it is its for extremely dry skin and I used this other stuff that was supposed to help by blistex. Should I see a doctor? It has like a slight yellow part but it's not very painful at all or anything I'm just not sure what to do..
