Blood sugar issues, maybe

Dreama
Sooo, I passed out at work today. I work in a nursing home, so the first thing I did upon waking is check my bp and blood sugar, both were withing normal range. I decided I'd rather be safe than sorry, so I came to the ER, since my doctor office wasn't open yet. An hour after the incident we checked everything again, and by bp was low, around 99/60, and my blood sugar was down to 56. I, of course, will be talking to my doctor, but has anyone else experienced this?
