I Was Fitted With An Intermedullary Nail In 1999 Following

I was fitted with an intermedullary nail in 1999 following a car accident. Over the last couple of months, my hip has become extremely painful. If I place my hand on my right hip while I walk, I can feel my hip joint grind. I had an xtray and everything seems ok. However, I have been referred for an MRI. Just waiting for an appointment. The pain is intense. Appreciate any advice. Regards John.
