I have recently suffered terrible sunburn. my legs had swollen to almost double the size and I could not walk, I believe I had Sun exhaustion because I had passed out from this, now a few days later the rest of the sunburn on my body is beginning to peel and wear away but my legs are not dry or peely at all, they are a dark splotchy purple color, it looks like burst blood vessels. Is this serious or will it fade like to sunburn? Do I need to watch for anything?
