Soreness

Has anyone experienced soreness in their stomach weeks after their surgery? I'm five weeks out and went back to work a week ago. I have primarily a desk job and have noticed that my stomach is very sore where I had my surgery. Not on the outside where my incisions are, but inside, like I've been doing hundreds of crunches. I contacted my surgeon about it, and he doesn't know what to make of it. I'm thinking it's from all the sitting I do at my job, but I'm not sure. I also notice that sometimes if I bend a certain way, I feel like inside I can feel "hardness," almost like I can feel the staples around my new pouch. Has anyone had the same experience? Does it go away? Any comments would be appreciated.

I've not had the surgery yet but it may be scar tissue, I would get a second opinion
