Hi- yes I had the same issue with one of my incisions. I used hydrocortisone cream and it eventually went away. Mine was a reaction to the steri- strips. You should watch them and if they get bigger or have a discharge at all call and go see your doctor.
Jay that is the food addiction talking to you...be strong...remember when we used to feel low we would turn to food for comfort...you will have to look for new things to turn to...this will pass!
