Yesterday i hurt my foot pretty bad jumping down the stairs, the pain is bearable but i'm hearing and feel like a clicking or grinding noise, is it broken?

Foot pain: Your feet may feel pain after an injury. It is normal to feel less pain as the days pass. Prolonged pain may be due to an undiagnosed condition such as a stress fracture. I would recommend you see a doctor and get some xrays.

See A Podiatrist: It may be broken or you may have sprained a ligament. In either case, time is of the essence and i would strongly suggest seeking care from a podiatrist to minimize any further damage. Otherwise you may develop arthritis and instability in the future and it may never heal correctly.
