Does Lipo "pre-tunneling" involve heat and fat redistribution?

My doctor performed lipo on my thighs, and what he called "pre-tunneling" to prevent ripples. After the procedure I've learned he did fat redistribution which I did not consent to. I've also had a rough recovery, because of nerve pain. Does pre-tunneling involve heating the fat, which may have irritated the nerves more than just traditional lipo? Does pre-tunneling typically involve fat redistribution? I thought fat redistribution is another word for fat grafting.
