My mother in law has has heart problems, on blood thinners and blood pressure medicine for 20 plus years. A month ago she fainted several times and ended up in the ER. When she stands her bllod pressure drops to very low. The doctor put in a pacemaker a week before her 90th birthday, took her off blood thinners and is trying to manage jumps between high and low blood pressure, low blood sodium, heart rate and repaededted UTIs. My husband and I live 600 miles away and when we have visited we have not cuaght the doctor. My father in law, sister in law and bother in law all see her daily and the doctor most days. She is back and forth from rehab to the hospital. The problem is they don't ask the doctor anything and my husband and I can't find anything out. They all just act like she she will spring back and go home to live. On top of it she has dementia. How can I guage what is going on?
