My 93-year-old mother has been in bed for two days, "tired". She vomited a time or two, and has had black, horrible-smelling bowel movements three or four times in the two days. I will check her b.p. tomorrow, but wondered if those are the symptoms to anything that jumps to mind. Her blood pressure med was doubled a month or so ago, but no other changes and she's in really good health otherwise.
