Sassy's Up Late Again

Once again, I stumble home like I'm walking on broken bones. I've noticed after a day when my thighs are particularly stiff, they actually radiate heat. The skin is noticeably warmer than anywhere else. My chest is flushed and I have a faint rash on my thighs--I've ignored it for a while because I wrote it off as just ingrown hairs from friction or too-tight pants. But I've been wearing loose pants every day for a couple of weeks now, and I still have tiny bright red spots on my "lap" area of my thighs.
