Thank you for the query.
Horse fall offs are quite dangerous and can cause serious injuries. Even if the symptoms does not indicate it. Even if there is no bruise
visible, muscles or even bones could be injured. That is why after such trauma is is advisable to have some diagnostics and rule out serious problems.
and leg pain can indicate broken ribs
, spine fractures, hip fractures or leg fracture. Moreover if the rib is broken, there is always a risk of pneumothorax
what can be life threatening. Abdominal traumas should be always ruled out.
I suggest you to visit your doctor and have chest X-ray, ribs X-ray, spine X-ray (CT would be better), abdominal ultrasound
, hip X-ray and leg X-ray.
Hope this will help.
