I had my PCP look at it and she said it was probably a hernia because it's located directly on the incision site. There's nothing to indicate an infection. She said to not do anything at this point. I had a drainage bag for two weeks after surgery so the seroma isn't likely.

I'm not happy with being uncomfortable and with the look of my abdomen, but more importantly, I have read that not doing anything can make the hernia larger and more challenging to repair. I'm not done with my decision of what to do yet. Need to talk to colorectal surgeon who did the resection next.
