Hip Pain One Year After Small Amount of Liposuction - What Could Be Wrong?

I had a small amount of lipo on my hips done a year ago. The bruises on the left side were very bad, much worse than the right side after the procedure, I had sharp pains from word go and couldnt lay on my left side for sometime. I spoke with my Surgeon and Gp in the early days, both said it was fine. The pain went away but now its back, sharp pains, burning sensation and some days I find I am limping with the discomfort. I am very slim,100ml was taken from both sides. Does this sound serious?
