Hi Tracy 17871 and welcome to the forums. I'm assuming that you've not been diagnosed as your info says you're pre-diabetes? Please correct me if I'm wrong. It also helps if you give us a bit more info - what your HbA1c score was, what you're eating, that sort of thing.
No-one on these forums can or should attempt to diagnose. However - not everything is blood sugar related, and things you experience can have other causes too. In the past I had similar sensations to yours with low blood pressure, for example, but I am not saying that is what you're experiencing, I have no way of knowing. My advice would be to see your doctor, if you can.
