As directed, I give my shots in all 8 locations (thigh, stomach, back of upper arm, back hip). My wife helps me with the
shots in the back of the upper arm, and the
shots in the back hips). I have made sure to do the same progression, since I began, so I do not return to the same general area, until 7 shots later.
I found that the shots in the back of my upper arms, usually stung the most.
I was surprised when I began taking the shots, that I usually never felt a thing.
