I Got A Sunburn Approx 2wks Ago On My Shins

I got a sunburn approx 2wks ago on my shins and ankles and top of the feet. The peeling has pretty much stopped but I developed red/purple areas on the top of my feet and ankles and they are very sensitive/painful and feet/ankles swell. It hurts to walk when the swell and they also have a burning sensation constantly. I would like to know if I'm ok and what I should do to alleviate the symptoms of pain,swelling and purple color
