So is PPPD different for everyone?

As I read through this sub I see lots of different “triggers” and symptoms. Mine happens to be driving but yet others actually feel better behind the wheel. Some feel like they’re walking in clouds but others are ok in the daily grind. Is it possible there’s varying severity and symptoms? I would guess that to be true but seems like whatever this truly is seems to be a fairly new diagnosis (2017?) so maybe we’re still in the discovery phase. Just had that random thought and wanted to throw it out there.
