Tummy tuck and lymph system

I had a tummy tuck last march. I have not scarred well and took a very long time to heal. I had my drains in for over a month. Most people get theirs out in a week. I still have problems with swelling and my cellulite is worse than it has ever been. I am very thin and was before the surgery. I had a lot of loose skin and stretch marks from my 2 previous pregnancies. I did a couple of tests that I ordered on line for heavy metals and tested posative. I did a quick heavy metal cleanse and went to get my surgery. If I knew then what I know now. I started having breakouts about a year ago on my head and chin. I got my first stretch mark when I was 15 I started developing cellulit at 23 a few years after my tonsils were removed. I know now that my liver and lymph probably haven't been working very well for awhile. I am 36. I have been doing some dry skin brushing. And resumed my heavy metal cleanse. I did not scar well and was told I will need some kind of scar therapy. Is there a particular way for me to do the dry skin brushing. Have a permanently screwed up my lymph system with my tummy tuck and earlier tonsillectomy. I want to try and repair some of the damage that I ignorantly did to myself.
