I am not sure what the injury is, maybe a muscle or maybe a crushed disc which I have had before. I am waiting to get an xray. But lately I have a great deal of nausea and burping. I am taking therapy and the exercises are a little strenuous, so I wonder if they could be causing the nausea. When I had my pacemaker put in it was causing problems with the vagus nerve and that caused a lot of nausea and vomiting. Just wondering. Thanks.
