I fell and fractured my right radius a year ago. I had an MRI scan at the time which showed my lunate bone was dark. One consultant was concerned about this but at the fracture clinic they said it wasn't a problem. I have had a few twinges over the past year but now I find that fairly frequently I wake up and my wrist feels bruised and weak. Sometimes it feels better during the day, sometimes not. Should I request another MRI scan? What could be done anyway?
