I noticed a shiny red area of skin on my shin a few days after getting a severe sunburn. I had injured my foot a few weeks prior and got a boot put on for the following 3 weeks. During this time, the rash didn't go away nor did it spread. I have no itching or pain from it. I was put on an anti-inflammatory, meloxican, for the entirety of my injury- before cast thru taking it off about a week ago. I have been out of the boot for a little under a week now and the area that was red and shiny has become more scaly and a little more of a purple tone- barely noticeable. Still no symptoms. What do you think this could be?
