Yesterday, I didn’t eat anything before work but I had 2 cups of coffee. I work in a clothing store so I stand all day, or put clothes away. While putting some clothes away, I suddenly felt my heart beat very intensely, then my entire body felt heavy, like I was sinking. My head felt heavy and I lost focus for a minute. I sat down and drank water and ate a bag of pretzels, but eventually went home where I had some soup and laid down. Today I still feel a bit off & my left arm feels almost numb.
