I am concerned about this being a TIA. I am physically OK. I have not had a physical in a great many years. I am feeling better today. I hope I do not go through that again. A web page says this can happen to the average person. I suspect it would be very rare. If this is true, I still do not think it would happen to them to the extent that I had experienced. This may be related to anxiety. I need to get myself checked out. I had this happen to me maybe about five years ago. In this case, it was much wirse. However, it only lasted several minutes.
