For the past few months I've been having these little "episodes" where I overheat and get very lightheaded, weak, and shaky and it gets hard to breathe. I work at a movie theatre so it's very hot being surrounded by warmers, ovens, and a popcorn popper for hours. Last night I got to the point that I nearly passed out and almost fell over and I had to be driven home. Usually sitting down for a bit helps me feel better, but last night it didn't go away until I was driven home and rested overnight. I'm just wondering if anyone has any idea of what's going on? I'm always hydrated and I eat enough so I don't have any idea. Recently it's been happening almost every day I work and I'm not recovering very well from it Just last night it happened again and my hands felt so tingly and numb along with all the other mentioned symptoms it usually happens with heat or too much movement
