shot in my right quad on the 12th, let quad on the 14th, right glute on the 16th, and left glute today. have flu symptoms, cold sweats, chills, insomnia. the pain does get bearable after a while, you get used to it and it doesnt hurt as much anymore. just make sure you shoot it in the morning and not at night before you sleep. thatll let it spread during the day.
