I just got back from Mayo's Pediatric Pain Rehabilitation Program. I had many of the same concerns that you all do when I went, but it worked for me! I went in a wheelchair and using a feeding tube, and left walking and eating everything by mouth. We're fairly sure I have mitochondrial disease, which is progressive and life-threatening-- so I am certainly not one of those kids that would naturally improve anyway. I am not cured, and I still have limitations, but my limitations are minuscule compared to what they were. There are still some things about the program I'm not a huge fan of, but as a whole, it was miraculous.
