Over the last year or so I've noticed that going on a swing (for no more than about 5 seconds) makes me feel dizzy. It's the same with bouncy castles and can't even manage one verse of ring-a-ring o' roses!
Is this just an added joy of ageing?! I'm 38 which I didn't think was too old to manage on a swing! Or maybe something inner ear related to get checked out (obvs don't want to waste a GPs time) !
