I have a question. Is it possible due to an injury to my upper back that there was damage to a nerve that would also cause A-Fib symptoms? I have been studying this possibility because I had an injury a herniated disk with so much pain in my upper back. I am 65. A few months later was doing a lot of scrubbing and general cleaning but was bending over and using my arms and shoulders for lifting as well. Soon after had an attack of a racing heart and shortness of breath. Was rushed to the ER and was admitted to the hospital over night. Soon after admitting the racing heart stopped on its own and breathing was back to normal. They couldn't find anything wrong. I was set up with a Cardio and had all the tests. Wore a monitor over a few days. They could find nothing wrong with my heart said it was A-Fib and put me on toprol and low dose aspirin. Said go home that's all that could be done. If it got worse come back. The only time I have these attacks is when I over do and do too much physical work that involves my back and shoulders and arms. Also I seem to be able to help it to ease a little just by changing position and it only seems to happen after going to sleep. I sleep hard and don't seem to change position and when I wake the back of my head is numb and now I notice that the tip of my nose gets numb at different times depending on how I sit or stand. So does anyone know could this be caused by Peripheral Neuropathy? The Doctors that I question say you have A-Fib live with it. I doubt that. I think it may be something else. Any help would be greatly appreciated.
