I've had PCS for ~6 months, pretty typical array of symptoms from what I've read in many posts. I can see progress with many of the symptoms, except those relating to dizziness.

I am dizzy (feels like I'm a swaying tree in the wind) whenever I am around noise of any volume (if it is very soft it doesn't bother me), talk loudly, sing or laugh, when I move around, cough, sneeze, blow my nose, bend over, worsens if I do anything that gets my heart rate up (ridiculous things like going up stairs, whisking soup, walking up a hill). If I'm standing still, I sway slightly all the time, if I close my eyes the sway is more pronouced, same if it is dark. I am easily unbalanced. Nausea accompanies the dizziness. My eyes feel weird, heavy and my vision blurs a little in spurts when I feel dizzy. It goes away if it is quiet and I hold still/lay down.

Is this similar to what's happening with others? Could you describe your experiences with this aspect of PCS? How long did it last, what was it like for you? Thanks!
