I just had a hernia repair and had a similar problem at the end of my incision. I know this sounds gross, but take a square piece of toilet paper and lightly press it on the
open area and then see if you smell anything. That's a pretty sure way to tell if it's an infection. Mine smelled pretty bad so I had a culture done on it. I work at a doctor's office, so it was easy for me to get it done. I ended up having a wound infection and a two-week course of antibiotics cleared it up and it finally closed. Good luck.
