Leg Pain Diagnosis Diagnosis On Pain Along The Top Of The Foot?

Diagnosis on pain along the top of the foot? - leg pain diagnosis

My father has experienced some foot pain on top of the foot in the city, where it connects to your leg. It is of course a little swollen and bruised. He said that) the pain away for your everyday tasks, walking or standing (applied pressure. But when he sits down and takes the pressure of the foot, it begins to vibrate. "It's like when someone knocks and repeatedly with a hammer."

Can someone tell me what the diagnosis for your problem?
Thanks
