Somethings not quite right

Went out to Elk Lake today while on my split to get a run in of 20+ km. I was feeling really good, and I started off strong. Then I felt a very uncomfortable feeling from my belly. The usually soft bit of tissue that comes through my hernia was hard and sore as hell. I stopped and held my guts for a minute or two. I couldn't push the tissue back in like usual. I sat down and tried to relax as it was more uncomfortable than anything else. After about five minutes it settled down enough to go away. I was a little spooked to run again but tried it out and didn't have a reoccurance so I hammered the last km, just to see. I was fine but what the fuck anyway? I was just at the doctors office last Tuesday and said that I really didn't need to have it repaired. Now what? 23:13 ~ 5km, 4:39 per km.
