Cardiac Autonomic Neuropathy aka CAN. It’s not easy to deal with. I went to the grocery store. I decided to walk instead of a cart. Big mistake got dizzylight headed my Bp was 96/50. It went back up in five minutes sometimes it’s 159/100 wait 10minutez it should start coming down. You get arrhythmias heart beats too slow or too fast. Once it’s in your heart not much you can do. After, my diagnosis I was told by the electrophysiologist you have eight years left to live. Mine is autoimmune problems.
