I am 12 days post op from liposuction. I was very surprised to find my incisions were stitched closed and I had NO drainage. I thought my surgeon said he used tumescent and no sutures. Anyway, I see some results in the abdomen, but my back is very swollen and there are some large, hard sensitive areas on my flanks.My lower body does not "seem" to be swollen but also doesn't seem changed. What is the likely cause of the lumps and is it OK? For the body parts that do not seem swollen, should I see future results or is this it? Why no drainage?
