Trampoline causing headaches

[MESSING2]

DD (11) sometimes reports she can feel her brain bouncing around in her head when jumping on a trampoline (not particular violently) and it causes pain in the scalp area. I tell her to stop bouncing when it happens, just wondered if anyone else has experienced this and if it's anything to trouble a GP about?
She's otherwise fit and healthy.

I wouldn’t worry if it’s only on them that it happens. When I’m made
to go on trampolines I feel the same way!

I'd make sure she's drinking enough water

Thanks for the replies, that's reassuring.
