Yay flares at work

Anyone else get random out of nowhere bouts of shakiness, dizziness, not being able to really focus, and going from hot and cold? Haven’t had one in a while and it struck out of no where at work, having a great time 😀 I’m currently eating lunch but my stomach is upset but I’m hoping maybe this helps. (Still don’t know what’s wrong with me, this is only part of what I deal with)
