Thank you for your prayers. The doctors could not find anything, except that he was also anemic. They decided it must be a slow leak caused by his blood-thinning medication. He will have a procedure later to block off a small appendage on his heart which is usually the problem. It will not be open-heart surgery, just a small tube inserted from his groin up to the heart. After that, no more blood thinner.
Oh, and his roommate was kind of deaf and obnoxious, but he talked loudly about Jesus for three days!
