my grandma was just release from hospital for a stroke about a month ago. She was told then that she has had hign blood pressure for years and multiple strokes that she didn't know about. Now she is back at the emergency room tonight on 4th of July, because she is very weak (she cant walk) and very confused (she thinks today is thanksgiving). My family first thoughts were she had another stroke. The emergency room is saying she has a kidney infection. This doesnt make sense. It doesnt explain her confussion or weakness. Does this sound like a correct diagnosis?
