Update #7
PT apptmt on 4/23 went well with no needling necessary. PT indicated that the abdominal area had loosened up, but there were still issues with left psoas.
The thoracic back muscles started compensating for the improved abdominal muscle function. PT called this "peeling back the layers of dysfunction." Seems that the body (esp a 48-year old body that has to sit for his job) will find all kinds of creative ways to compensate.
She gave me the 2nd green light to start some running. (I was too afraid to run after the 1st green light in early April). So a few days ago I started 2 min run alternating with 2 min walk for 10 reps. I walk 10 min+ to warm-up and cool down.
After 2 runs, it is going pretty well. Only a very slight sensation can be felt in the lower abdominal/inguinal area.
Workouts at the gym now include a variety of lunges (front, diagonal, side, back) to keep the hip joint open, strong, and flexible.
Took the Functional Movement Screen 2 weeks ago and scored 17. I was expecting a 14. This gave me some confidence to start some easy running.
One stretch that seems to help: stand your with your side one arm's length away from the backrest of a bench or chair (with a height of roughly midthigh). Take the nearest foot and place it on the backrest with the foot, knee and leg pointing perpendicular to the direction you are facing. This will initially be felt in upper hamstring/pelvis of the raised leg. Gradually bend the knee of the raised leg so that the straight leg abducts and a stretch is felt in the groin of the same leg. Hold for 1 min and switch sides. Try to keep the hips facing forward and perpendicular to the raised leg.
I am becoming convinced that the sports hernia is correctable without surgery.
Next update coming in mid May.
