hi I just got home from the hospital , I had an allergy shot and I broke out in hives on mostly my arms, both sides, and my pelvic region, was hard to breathe, they gave me Benadryl and adrenaline , the bendryl didn't work but after that adrenaline its fading, I still have the iv taped and wrapped because I might need another one in the morning, its pretty annoying ..will I need that other shot/dose ?do you think I should take it out ? can the allergic reaction come back?
