UPDATE: mom has congestive heart failure. They took a echocardiogram (not how it's really spelled) and the results worried the doctor so tomorrow they are scoping her artery that goes to her heart and will have a look through the camera at what damage has been done. She's not happy about taking more meds(she hates taking meds) but she isn't complaining because she knows that it's what's keeping her alive right now. She's also not thrilled about using oxygen but knows it part of the package deal. She might just have to use it now and then, not constantly.
