What Treatment Can Address Red Bumps/Pimples After Waxing? (Photos)

I got waxing done on my back 10 days back for the first time.Since then I have noticed red pimple kind of spots on my back. I am applying Calamine lotion and Fucibet cream (fusidic acid, betamethasone valerate) on my back from last 3 days but not seeing much improvement. Can you suggest what I must do to get rid of them? Mistake that I did was I should have put ice after getting waxing done. I have sensitive skin. Please suggest a treatment for this problem.
