It has been 4 1/2 months since I had lipo of the stomach, flanks, bra line, and inner thighs. I still have what looks like faint, almost lacy-looking bruising on my hips and darker coloration on my inner thighs still. My doctor now thinks I have hyperpigmentation, rather than bruising. However, when I researched it, I came up with three options it could be that I listed in the title of the question. They all seem to cover my issue, though, so what is the difference between the three?
