Did you get the med to room temperature? I find that when i dont leave the med out long enough, it stings at time of injection. The red spots will go away, or at least they did for me. I used to have them all over and now very rarely. The nurse at mslifeline told me to try a warm compress, it will give relief also with the sting.
