You are about the point where the dissolvable stitches are dissolving. When they do the tension they were taking goes to the muscles and can cause this. I had it with several of mine.
If it the middle low one just make sure to feel the middle of it and be sure it isn't pulling apart. This would be a hernia. You may feel a small amount of a gap at the skin, but it shouldn't go very deep.
After my open nissen I have a slight muscle separation and have to keep an eye on it. But it's the 4th time that same area was cut open.
