my mother has had very high blood pressure for the last 6 months. She is suppose to have hip replacement surgery. The Doctors say they can't until they get her blood pressure under control.My mother tells me they keep adjusting her medicine but to no avail. It's hard for me to believe it has taken 6 months for them to get it low enough to have the surgery. my question is is my mother fibbing to me because she is scared to have the surgery or is it that difficult to to get someone's blood pressure lowered?
