Hi there. I'm fairly new to this board but I will pitch in and say what my experience is regarding nausea and PCS. My initial nausea was due to dizziness or a sense of lightheadedness after my fall, especially when I was moving in a vehicle. The worst of it gradually went away, but even now, 3 months post fall, I do still experience lightheadedness and sometimes nausea.

What's helping me now with this is a set of "Habituation Exercises" I got from a physiotherapist specializing in balance and dizziness. These are like exercises figure skaters do in order to be able to spin without getting dizzy. The exercises seem a bit silly, but they are really working for me. It's like I retraining my brain to orient itself after moving and I'm feeling better.

I had a setback a couple of weeks ago and stopped the exercises and the dizziness returned. Since starting up again, I can definitely say they are helping.

Good luck
