I have a swelling on one side of my abdominal area above my penis, it is not sore to the touch, the only pain i am experiencing is in my lower leg and discomfort when walking. is this sign of a hernia or groin injury. i no longer play sports, as i have had both knees replaced and two yrs ago, broke my femur bone in three places due to a fall. i spend a lot of time mowing on a riding lawn mower, thats about the extent of my work these days.
