What Is The Treatment For Sunburn , Acne And Rash?

I got a decently bad sunburn a couple weekends ago and most of my skin on my front side peeled. Now, a couple weeks later, there are two spots, one on me chest and the other spot on my abdomen, that have a sort of rash. It doesn't itch or anything, but it is red bumps, almost looking like acne but it's not. Was wondering if there was a way to help them go away, or if they will on their own? And also, if I should stay out of the sun mostly until they do subside.
