Pap-Pap in the Hospital

Friday my father-in-law started having very sharp stomach type pains and his blood pressure dropped to where he couldn't see it register on his sphigmomanometer. Mother-in-law took him to the emergency room, assuming the logical, which that one of his ulcers had started to bleed again, but apparently that's not it. He was admitted and is still there and they still don't know what's going on, other than that he has some kind of infection, for which he is getting IV antibiotics. He's feeling better enough to get crabby about having to stay there, so that's a good sign. He told Mom he was ready to hitchhike home if she wouldn't drive him.
