Why does it feel like my brain is moving when i'm jumping on trampoline? it's not horrible pain but i can feel it and i don't like it.

While not a common: complaint, other people describe this. There is not an obvious explanation for it. It does not seem to be associated with epilepsy/seizures or other serious neurologic disease. Consider whether you have any other neurologic symptoms: weakness or numbness in the arms or legs, imbalance, vision changes, headache. Possibly related to eustachian tube dysfunction in inner ear. If none, avoid jumping:)
