I have begun to feel a very sharp pain in my left elbow if I lean on it, I fell down the stairs 6 months ago and cracked the bones in my left wrist. Is this a belated injury from the same accident - a chip of bone? and will it move and cause me further injury? at the moment i feel no swelling other than the sharp pain when I lean on the elbow - like a sharp pin. Should I ignore it or have it checked out?
