Today 4/4/17: Huge hard ball on my hip at fat insertion site, 3 months post-op lipo and bbl. (photos)

Can't get a hold of my doctor but where I get my massage I was told it's a ball of fat and they should do cavitation on it. I also have little tinny hard balls in my butt ( after bbl) and it still sore and hurts when I put on jeans or sit to long I get a lil tingly sensation. What do you recommend please? I was told it could be an infection but I have no fever or chills, no signs of one. Last week the one of the balls in my butt was a color darker, like a dark shadow and i get it in my hips also
