I get the CH at least 3 times a week for 3 months of the year. I am 27 now and started getting them when I was 22.
In terms of pain, I have snapped my tibia at 90 degrees whilst skiing and that pain is no where near the level of my CH.
My ch take roughly 5-10 minutes to hit the max which means by 15 minutes I generally pass out from the pain.
If this is the case for anyone, I highly suggest getting straight onto a bed or couch when you feel it coming on.
Nothing worse than waking up from a CH with a concussion.
