Had 2 si joint injections on, monday. Now I have 2 swollen red dots where the needles went in and they kind hurt and itch. Is that normal?

Can be normal. Injection sites can often have red dots or mild inflammation around them for a short time. Keep an eye on it -- if it gets worse (hot and swollen or painful) or if you develop fevers/chills then see your doctor right away. I have also seen patients develop irritation from the cleansing solution used on the skin. Sometimes this requires a topical steroid cream... Check with your doctor .
