I had the same happen to me both time that I broke my ribs and when I sent down a flight of stairs counting the steps with my coccyx.....far too young to have caused any damage... Or my father who went to the same A&E having plummeted over 40ft into a drystone brick wall after the thermal (hot air pocket) dropped causing his paraglider to fold and drop him like a dead weight.....they never even xray-ed him......the 2nd a&e discovered fractures in 6 vertebrae.....but he was far to young to have an injury (at 44)...
