Red dots all over my legs after waxing?

I've waxed my legs myself before but this is the first time I've ever had red dots all over my legs. They are tiny and there must be millions of them. It took maybe a day or two for them to show up, and as the days went by they've been getting darker. It's been a week now and the red little dots are still all over and it looks really discusting. What do you think it's from? Allergies? Something about follicles? When will they go away? Is it serious?
