Though I havn't had ridges under my skin, I have quite a few lumps, that are next to bone. They were all over my face, from the size of a pin head to the size of a large marble. Most have gone away, some still remain. Every now and then, they leave in true morg fashion, breakout of the skin. IMO this is where the body walls off the morg to protect itself, unless it is the other way around, the morg walling off the body to protect itself. One or the other. It is all going away slowly.
