I was just sitting in my chair reading. Then all of the sudden I started feeling hot and needed to go to the bathroom (urinate). My stomach was a little upset but not much. But I started sweating a lot and felt trembly/shaky and weak all over. I thought if I had something cold it might cool me down. So I ate a popsicle and sat back down. I actually had trouble holding the popsicle because my hands were shaking so much. Still feeling really tired afterwards, but the sweating and light headiness settled down. But since it s settled down and I m not feeling as bad I just don t want to overreact. Should I be concerned?
