To people living in Texas and other parts of the South: NEVER LEAVE YOUR CLOTHES OR TOWELS ON THE FLOOR. Brown recluse spiders might take up home there. Symptoms of their bite are similar to this. (Had a friend go through that. No amputation but several weeks in the hospital and they had to take a chunk out of his leg.)
Nasty chemicals in those bites. Miniscule amount can destroy massive areas of tissue.
Terrible if they weaponized the stuff.
One of my friends here in Tennessee got bitten by a recluse in an inconvenient place putting on his boxers in the morning.
AMEN TO THAT! Clothes hamper is over the closet door and anything dropped on floor gets tossed into hamper ASAP and unless fabric cannot handle it ... clothes washed in HOT water. I figure 140 degrees should be hot enough to kill any critter that may wander into any of my clothes.
I may be a little neurotic but it beats necrotic any day.
