Are the red, hot, bulged-out from skin marks signs of infection after BBL fat transfer? (Photos)

Had a bbl via fat transfer one week ago. 3 days ago I noticed I had a few red spots on my left side butt cheek. The next day 08/08 I had fever twice, haven't had fever since. Contacted my surgeon in MX, he said this is normal and part of the new fat trying to establish blood supply...I'm freaking out since the red marks are getting larger and spreading. They are hot, red, firm like a beach ball, hurt, and slightly bulged out of my skin. Is this is normal or should go to the hospital?
