Hi and welcomte to HCM.
There is no need for further testing. If you didnt hit your head, or you dont have tingling
in legs, and you can move normaly there is really no reason to be concerned. This wasnt high energy injury
that could cause fracture
or internal organs injuries. Just be caotious in next few day.s If you notice blood in urine or stool, tingling around the body or strange badominal symptoms you should go to hospital. If not, just rest and take standard painkilers. WIsh you good health.
