Is this normal wound healing? Uncomfortable/slight painful little hole on nipple. 3 wks post breast lift with implants. (photo)

Hello! I had a crescent breast lift and breast augmentation about 3 weeks ago. Per my PS instructions , I took off the steri strips about a week ago. And I clean the wound doing the following: clean gloves and clean cotton balls/pads I use witch hazel, followed by hydrogen peroxide and then gently apply Neosporin. I wear cotton support bras to let the wound breathe but when I go to work , I place a little cotton pad between my nipples and the bra. Am I causing the little hole? What could it be?
