About three weeks ago at work, I was accidentally struck with a blunt object approximately four inches above my ankle. The wound was located about one and a half inch towards the inside of my calf, just beside the chin. I had localized bruising and pain that subsided with compression bandages and warm compresses during periods of inactivity. However, I have noticed that there is a lump formed beneath my skin. It is stiff but still malleable, but is still very sensitive. Could this be a sign of microfractures? I have no difficulty walking or standing for long periods of time. However, I have been told by my healthcare professionals that I have an incredibly high pain tolerance. Any answer, comment or insight is appreciated!
