Hi, I got a terrible sunburn last week on my legs. It blistered (2nd degree burns) on my feet, and the next two days I could hardly walk, and my legs were quite swollen. It's nearly a full week later, my legs are still red, but on patch has turned orange (around one spot, I dropped a weight on my ankle yesterday and a patch of skin came off, it is around that spot). What does the orange pigmentation mean?
