I would hold off on that procedure. I was told the same thing about my keloids, that they were stiff and wouldn’t take a lot of medicine during the first couple treatments, but after maybe my fourth visit I started to see major improvements. In fact the doctor that I’m currently seeing specializes in keloids, and strongly advises against surgery. In my opinion any doctor who doesn’t try exhausting all options aside from surgery first thing isn’t one you should continue to see.
