Any idea
how long the redness lasts? I did my first shot
last week, used my thigh.
A day later I got a "ring" of redness, just about the size of a nickel. Actually, it's about as close to a perfect circle as is humanly possible. It doesn't hurt or itch, isn't swollen or anything. Only the outer edge of the circle is red, not the area inside the circle. It's like a perfect little nickle sized ring on my leg.
Mainly, I'm just curious as to how long they might last.
