Why do blisters/pus spots keep forming on my areolea? (photos)

I've recently had a breast augumentation and lolli-pop lift. I am 5 weeks post op and I have blisters forming around my nipple. The blisters have popped and white & yellowery pus has come out. They have started to heal and a scab has formed but I can still see white pus on underneath, like it's ready to pop again. A few have! I have asked my surgeon for this opinion and he has told me to keep the areas clean by using an antiseptic liquid and cream, and reguarly change my dressings once a day.
