I don't think there is only one correct x, y, z order. It's all about giving the body the best environment to heal itself, which it is programmed to do (if it isn't some kind of unknown autoimmune reaction or something like this). So it might be necessary to do steps x, y, z, but not in that order necessarily :). This might be taking supplements for some people (maybe because their body doesn't resorb specific vitamins or minerals correctly), changing diet, excercising etc... The mindsef oft course also plays a big role, so being depressed (like I am a lot and badly these days) will probably hinder the condition from healing or going away "spontaneously" (Which I don't think is possible, at least with the more severe cases).
