My armpits HURT

I’ve never had this happen before. I use Dove deodorant but recently I’ve been using Secret because my Dove one finished. My armpits have been itching me for about a week now, if not more, but today I actually took a picture of them.

It burns so bad!! What is this and what can I do about it?
