My 80 yr old grandma had triple bypass heart surgery 2 weeks ago. Today has been the worst day yet. Some new symptoms are very dry mouth, dizziness, and she said it s hard to breath, like hard to catch a breath. I m worried. We ve been home from the hospital almost one week already. She has had normal pain and whatnot but today with the dry mouth and severe dizziness (she won t lift her head, looks down) and the hard time breathing... is this normal?
