Turns out it's cellulitis. I just happened to show it to someone who just happened to recognize it. Now that I know, I do realize the doctor did mention it (to me? to the nurse?) but that left me confused, because the only thing I knew within that word's family was cellulite, which has nothing to do with this...
Not only that, but the person who told me says that it may even have been what caused the migraine headaches and the nausea, as my body may have been starting to try to fight what was coming on. I'll never know for sure.
All I know is that right now, my leg still feels warm to the touch, and part of the rash has erupted into sunburn-like blisters. With the skin being stretched by the swelling, the mere act of walking can make those blisters burst and leak... Yuck!
Hopefully, the antibiotics will help. I sure hope so, because it's still slowly spreading! (The nurse took the time to delineate the rash-covered area with a felt pen, while I was there.) Fortunately, it is only spreading a little, as opposed to the rate of growth between Thursday night and Friday morning. I am to go back if it does not retreat or worse, if it spreads. I'm giving it one more day to test, as I have started taking the antibiotics already.
We'll see.
Except that in my case, the latter came before the former... what gives? Apparently, I can't even get sick right...Wikipedia wrote: This reddened skin or rash may signal a deeper, more serious infection of the inner layers of skin. Once below the skin, the bacteria can spread rapidly, entering the lymph nodes and the bloodstream and spreading throughout the body. This can result in influenza-like symptoms with a high temperature and sweating or feeling very cold with shaking, as the sufferer cannot get warm.

Or is it saying that the redness shows it has already infected the inner layers and progressed more rapidely than the redness will, hence the flu-like symptoms before the redness which would be sort of an after-effect of the deeper infection?
Either way, I don't get it.
