My husband has been having loose stools for over a year, with more frequency finding some blood in stool. He has had discomfort in general, fatigue, and gas/ heartburn. This past week he started having some facial swelling (which went away) lumps appearing and disappearing on his arms, legs, back, and groin, and continues to have severe itching in hands and forearms despite frequent Benadryl. Are all these tied together? I know he needs to go to doctor, but he keeps putting it off since we don't have insurance.
