I also had severe abdominal cramping about 40 minutes after my allergy shot. I have since been prescribed an epi pen should this happen again. This is an allergic reaction and requires attention, according to my allergist. He has changed the amount of allergen I'm given, as well as the timing of injections, to prevent another episode. I am not given my shots unless I have my epi pen with me. Hope this helps. If your allergist isn't taking this severe pain seriously, get a second opinion from an allergist affiliated with a university hospital.View Thread
