I was in Arizona with my mom a couple of years ago and fell asleep in the sun for 2-1/2 hours. I had had one Fat Tire Beer and nothing else. My mom eventually came and got me, I sort jumped out of the lounging chair which caused me to feel real dizzy, so I sat down. Then I walked inside my mom's house, my legs felt the same way (scorched), like blood vessels wanted to break, then I was standing beside her couch, ready to throw up, I fainted and hit my chin on the wood of the couch. My mom and my husband (fornicators at the time though ) carried me to the bath tub to put me in COLD water to revive me. My mom had called 911. Well, spent the afternoon in the emergency room hooked to an IV because I was severely dehydrated. Plenty of fluids is the right way to go. Yet, your legs are swelling too, you just may want to go see the doc....
Hope you feel better, I had second degree burns on my chest area since I had gone to Hawaii when I was 13 years old. When I am not tan, my chest area (under the neck, before the breasts ) has faint little red areas (in spots), not bumps, but little red circles. Its been that way since I burned so bad at the time.
Take care, I share your pain.
