What Is The Remedy For Sunburn?

Hi, I got sunburned the other day on my back, arms, and back of knees and legs. It s not blistering or even peeling though I think it will peel, it doesn t even look bad but it s one of the most painful sunburns I ve ever had. I can t walk without limping and can t sit or lie on my back without feeling immense pain. I had chills and was shaking earlier. I took a cool shower yesterday that didn t help at all, I ve put aloe on it and lotion but nothing s working, I tried ibuprofen and I ve been drinking lots of water but the pain and horrible burning refuses to ease down. Please let me know how I can make it go away faster.
