So around November of last year I started feeling off balanced / spaced out. it first started at work while I was just sitting there doing my work, I saw a doctor and he ruled out vertigo.. He checked my heart and recommended I'd see a cardiologist. My heart result's came back negative. has anyone else has had these type of symptoms? it seams like the off balance / spacey feeling get's worse when I move quickly / exercise. And the symptoms are everyday all day. I noticed when I lay down for a few minutes it get's better, but then soon after it comes back. Any suggestions?
