blueheron, yours is most likely the muscle going back together. it hurts! and you might get weird stabbing pains or dull aches for quite a while, i remember being like 9 months out and occasionally having an odd feeling in that area. It didn't hurt just was uncomfortable. It takes a long time for the muscles to grow back together, and you use your stomach muscles constantly. so they have a lot of strain on them anyway.
you mentioned your posture, be arefule that you don't hunch over to keep your stomach from hurting because then your back will hurt. It is not something you do on purpose, it just happens. i had that problem and didn't even realize i was doing it, and my back ended up hurting way worse than my stomach!
