my husband sometimes wakes up in the middle of the night with severe abd. cramps that instantly turns to diarrhea he then breaks out in a red rash on entire body including the whites of his eyes turn red, he feels extremely weak and almost passes out. This happens at least 1 time a month and always happens at night while asleep. Have gone to allergy DR who has ran numerous test and everything has turned out normal, I feel something else is going on but allergy dr just wants to see us again in 3 months. What other kind of Dr should we make an appt. with?
