Can I grow taller than that.

Actually I stand 5.10 in the morning, but reduces after some hours. I also experience that when I was 5.8, that was last year.

Your "height" doesn't grow and shrink throughout the day. Watch your shoulders and pay attention to how you slouch. It sounds like a posture issue, like you slouch more and more and the day goes on as you get more and more tired... assuming there's nothing medical/spine-like going on.
