My first two pins were in my quads not to bad Decided to do shoulders, not to much pip but following day I experienced some redness on my delt. Was not warm a little sore. It has slowly gone away. I have a good female friend who is a nurse but she works in pediatrics. Showed her she said looks like mild allergic reaction. She does not have much experience with test injections. Any opinions. Feel fine and redness is gone.
