Air bubbles, drainage and if this is normal. (Photo)

I got a bbl done in January. I obviously got lipo done on my belly, but I've been having problems with the left side of my belly. First I want to say that after surgery I had to get that side drained every week for 3 weeks. Now two months later it's still swollen and there's no fluid but it feels like air is in there. Is this normal? I was told by the office that it'll go away that it's just swollen. See pic below.
