Had anaphylaxis 12 weeks ago (tongue swelling, rash, short of breath) to x-ray dye, biphasic then protracted. On 5 antihistamines, 2 mast cell stabilizers and steroids still with some symptoms.Dont know if this is IA or MCAD. ALso now having trouble getting off steroids--?Adrenal insufficiency? Recently switched from prednisone to hydrocortisone. So afraid, don't know what's going to happen. Has anyone experienced this? Miss my old normal life.
