My mom is doing fine again. Tests have shown that it’s not a cardiac problem (like arrhythmias or blocked arteries again), but that her blood pressure sometimes is too high and sometimes too low and that it either spikes or drops without much warning or without obvious reason. She most probably has to change some of the meds she is already taking and the right medication and dosage still has to be determined. Nothing much is happening in a hospital on the weekend, so she most probably has to stay there for a couple of days. But all in all, she is doing fine. Thank God.
