its big like a 1/2 dollar bill, red in a circle shape and warm. i asked my mom and she thinks its a zit... on my leg!!?? never happened before. vickie thinks a bug would of bite me. it freaking hurts. a few years ago, joni got an ingrown hair on her leg... turned out to dig a hole and became black. ended up getting meds and $$bills. i sure hope it doesnt get to that point.
