Sometimes, when I have sex or engage in other highly physical activities I get this sharp pain in my abdomen, maybe an inch above my bellybutton and an inch to the left, as well as a more general pain that switches from my lower left side to my lower right side,
and back again. This is accompanied by a visible
and palpable protrusion of the abdominal muscle directly under the skin where the sharp pain is located. The pain there intensifies to the point where it's unbearable.
