30 year old male, has Crohns. He takes Pantoprazole, 40 mg. Broke out in hives around 3pm 11/3, yesterday. Had swollen feet and chest tightness. ER around 6pm, said take more Benadryl and sent him home. Hives and swelling settled down. 4am this morning, 11/4/17, hives returned and Benadryl didn t help. Urgent care @ 9am prescribed hydrocortisone and to take ibuprofen. Knees are swollen and hives are still widespread at this time, 2:50 pm. Any suggestions would be most helpful. Thank you
