Pubic area pain and swelling 4.5 weeks post op tummy tuck.

I had a full tummy tuck on October 20th. I have been doing fantastic so far. The other day my scar flared up over my hip and I went to ER and was diagnosed with cellulitis. I was placed on IV ABX and feel so much better. My problem is now my pubic area is extremely swollen. It also feels as though maybe my pubic area is bruised right along the bones. It's very tender and I am confused as to why this is happening now. Any advice on how to get this swelling and pain gone is much appreciated.
