I got a sharp pain in hip after riding horse pain not so bad now but has moved down leg . lower leg and heal num . what to do?

Nerve irritation: If your feeling numbness down the leg for more than a few minutes after changing position it could mean nerve impingement. Could be anywhere from the spine to the toes. All depends where the damage was. Sometimes it's as simple as pressure over a nerve where it crosses a bone. Other times it can be more complex. If it doesn't go away after a while follow up with your doc.
