I was thinking Fibro before I read down to where you mentioned it. A lot of us with RSD end up with Fibro which is all over pain. There are also triggerpoints too. There are 18 of them that go with Fibro. The lumps can be felt in the neck in the back of the arms, the knees, and the hips and but area.
You can go into a Fibro website and it wills how the 18 points.

It seems like we always get other things with RSD. Cronic Fatigue comes with Fibro most of the time too.
