Sports hernia info:

The pain from a sports hernia usually begins slowly. There are different theories about how this hernia occurs. One possibility is that tight or strong hip flexor muscles tilt the pelvis forward and stretch the lower abdominal wall muscles, eventually leading to small tears in the muscles and tissues.

Activities that require a lot of bending over and leaning forward can lead to this problem. Athletes who play soccer, ice hockey, rugby, field hockey, tennis, or run track are most likely to get a sports hernia.

What are the symptoms?
Symptoms include:
lower abdominal pain
groin pain
pain just on one side
pain that is usually worse with sudden movements such as sprinting, kicking, side-stepping, sneezing, or coughing.

Pain that is usually worse with sudden movements such as sprinting, kicking, side-stepping, sneezing, or coughing, or being hit by unblocked, qb-seeking, defensive backs like, say, Dallas's Roy Williams.
