Some people find that icing the area beforehand helps lessen the pain.
Some people find that lying down for the big shots helps, but only if your partner still feels comfortable giving the shot that way. Try a warm, wonderful bubble bath after your shot. You may find yourself looking forward to the bath, and which will give you something positive to focus on. Line up who will do shots, or learn how to do them yourself before you get stuck alone. Make up a daily chart of what medication to take.
