I've had 3 abdominal surgeries and experienced this sort of thing with all 3. No need to put gauze over the area. It may mean that the stitches weren't done as tightly as at the other end. It's not a problem even if there is a bit of oozing. I've had that, too.
I had stitches coming to the surface for months after one of the surgeries. They were supposed to dissolve but worked their way to the surface as they were doing that. I just pulled them the rest of the way out. If they are hard to tug, then just leave them alone. They will eventually loosen up.
It will take months before it starts to fade. After a couple of years one of my scars was barely visible. The last two are still red after several years. The difference, I suspect, was my age at the time of surgery. We heal more quickly when we're young.
I've tried Vitamin E and saw no difference between the time I used it and the next time when I didn't.
