Recently I was doing physical therapy due to back problems and during one of the exercises, I passed out. I had felt a bit lightheaded and black spots appeared in my vision. I completely blacked out and collapsed. I woke up about 10 minutes later. The nurses had been called into the physical therapy room (I was doing the therapy at a local hospital) and I was laid down across a stretcher. My blood sugar was extremely low, I believe they said it was 52, and my blood pressure was 55/27 or 28. They gave me some water and a glass of juice to bring up the blood sugar and had me lay down. I was covered in sweat and my legs were very weak. They nurses said that while I was out, my right leg would jerk and my right hand would twitch slightly. My sugar leveled itself out within about 20-25 minutes, but then my heart rate shot up to 112, which they were concerned about because my heart rate is normally about 85-90. I was kept in observation for about 4 hours, but due to the quick drop and then the even quicker rise in blood pressure and heart rate, the doctors and nurses were extremely concerned. One of the volunteers who witnessed the whole debacle says she believed it may have been a seizure. The doctors never mentioned seizure, but I am very worried it could be a possibility.
If anyone has any insight (is it a seizure? If so, what kind? What else may have caused it? etc.) it would be greatly appreciated!!
