Hernia vs not hernia
If it's a hernia
, lump will fade away when you lay down with your knees bent; return when you cough
, strain or heavy lift.
If lump stays the same with position changes, it could be lymph node, pulled muscle, or bruise. Hernias stay the same or get worse, as they are the hole. The lump is an organ trying to escape through the hole. The hole/hernia should be surgically repaired.
