Adhesion?

Recently I've been doing p90 which involves weights and sculpting on one day and cardio the next. I've been doing the ab portion that comes with it as well (crunches) and nothing has been bothering me until this past week.

Usually I can feel my port (its moved though) but yesterday after doing my crunches I was pretty sore near my port area. I assumed it was nothing and just went on about my day.

Today after doing push-ups I realized that the area near my port incision was sort of tender. If I touch it it hurts. If I press a little bit I feel something about the size of a ping pong ball. It's sort of hard but it hurts to push on.

Could this be an adhesion? This is the first time I've felt this and I just got off the treadmill and man did it hurt to run. I had to hold that area the entire time.

Any ideas? I don't see my surgeon until Sept. 13.
