I have hard lumps after Liposuction. Is this common?

I had my upper and lower abs, thigh and flank areas done. I now have bruised, hard and swollen lumps. I have a big one in my groin area which I should not of have because I didn't have work done down there. I know swelling and bruising are common, but hard lumps?? and in my groin? Is this common? Is there anything I can do to reduce it? I also have a weak stream when peeing a few days later also...please help!
