Ever since I was a teen my mom had a horrible allergy to milk protein. She was so sensitive to milk protein that even a single slice of store bought bread could affect her. Her symptoms were flu like as opposed to skin swelling or other more typical allergic type reactions. She visited Derek Roche at Sunrise Health Centre on Riverside Dr a few years ago and has been able to consume milk products without issue ever since. She does have to go back in every year or two to get "topped up" as she says. It took one or two treatments initially. It was really freaky. Both my wife and I have seen Derek since then, due exclusively to mom's success, and though we haven't had as pronounced a change, we have both felt it was beneficial in terms of treating allergies/chemical sensitivities. I have no idea if Derek would be as effective for stuff like chronic pain/injuries, but I don't see why he would only be good at working with allergies/sensitivities and not other stuff.
