Is this normal or signs of infection after otoplasty ?

Hi! I had otoplasty three days ago and still have that dressing. The first two days were fine, some discomfort but it wasn't anything out of the ordinary. Now on the third day my left ear began feeling swollen and hot. I can feel a tingling sensation and the ear throbbing. It doesn't hurt but I can still feel it being kinda hot, swollen, throbbing and tingle. But once again it doesn't hurt. Is this normal when the ear is healing or are these signs of infection? Or even worse, cauliflowerear?
