hurt heel and ankle

A week and a half ago I tripped over a sidewalk and landed hard on my left foot and my other shoe flew off my foot. I came very close to falling on my face. I went to the walk in clinic on monday after almost a week of walking it on my toes.
They said that I just bruised my heel. They gave me crutches and said to stay off my foot for a week. I have and my foot still hurts. The xrays say that nothing is broken. I still can’t walk on it. It sends a sharp pain up my leg. When I bend my toes it it really hurts my ankle. Should I see another doctor?
