hi my boyfriend was out shoveling snow for about 5 hrs today, this after noon he looked down at his wrist and there is a lump that looks like a bone trying to come thru his wrist, its on his left hand and its on the right side of his wrist, its not swelled or black n blue or nothing, he says its a little sore, I thought it might be an over worked muscle, should he get it checked, thank you
