I just came back to work after being laid off for construction. It's not a stressful job, and I don't run around. I stand at a register all day. Well I all of a sudden feel like I'm gonna pass out. My heart is pounding, I feel out of breath, and my arms feel heavy. I have sat down for a few minutes, but I've been here for over 5 hours. Anyone have this issue? 35 weeks
