I did, however, develop some really weird
symptoms almost immediately after taking the
Bystolic. I would notice that I would feel really light headed and maybe even a little nauseous immediately after taking the Bystolic. Also, I developed a very weird feeling in my chest (not the entire chest like before, but only in the left side, around the heart). It is a hard feeling to describe, but it is more like a soreness, not a pain. My left arm also started to twitch at random intervals.
