How Much Longer Is This Sunburn Gonna Last?

It's On My Shoulders and Back. It's pretty bad. It hasn't peeled (pealed?) yet. I got it on Thursday at the beach. I put no sun block on (regret doing that) and i was out for about 4 hours. But I put ice on it, I've been taking cooler showers, and I'm putting lotion and aloe vera gel on it. How much longer do you think the pain is gonna last? thanks
