When i walk i feel a bone pressing against the outer side of my foot. it's the worst pain i've ever felt in my life. should i go to the hospital?

Yes: With pain that intense you should definitely be evaluated. It could be from a variety of reasons... tendon and nerve injuries can be just as painful for some patients as a bone injury. Best wishes!

Call a specialist..: More than likely. the emergency room will do no more than a specialist will do tomorrow. Save money and time by staying off of it, use crutches and make an appointment with a foot specialist or orthopedic surgeon at first light.X-rays and treatment plan came be done in one step.
