I injected quads yesterday. Mid-outer quad. Injection went smooth. Well it is a new day, and it is painful. There is no swelling, no warmth and no redness. However, I feel a bad pain from the injection site, all the way down to my knee. That means that half of my quad is in pain. It is in tthe muscle because I have been massaging it. It is most painful at the spot right above the knee. Is this normal? Thanks.
