Rethinking the primary problem in MS

I think it's possible the damage to myelin seen in MS may be caused by immune reactions to any of some number of possible antigens crossing the barrier in close proximity to it. Food antigens, infections, anything foreign that has DNA and can react with the myelin, making it appear foreign to immune cells which also cross the barrier at that point. The damage is often reversible. Many MS sufferers, including CP and SP, know that there are occasional moments of "lucidity" when the faculties lost (balance, walking, coordination, fine motor control, skin sensations, strength), return to near their original state. The problem is that whatever puts the body in this state is fleeting, and not maintained over a full day, or in some cases even for an hour. Until the core of the nerve is damaged the myelin is repairable with full recovery. Maybe the ability to do this repair has some lifetime limit that, once exceeded, puts a patient in the progressive category. Perhaps some have very little of this capability or their BBB breaches cover too much area and that's why they start off progressive. The fact that the faculties are lost again soon afterward may mean that the damage happens again to new myelin, perhaps only thinly applied, and perhaps the plaques are sites where repeated damage has occurred, thickening the myelin scars each time. LDN users and people who do a lot of exercise (like a body builder I know of who has MS) are aware that the repair process has something to do with their endorphin levels. In rehab this kind of health and stamina is built up via exercise which provokes the repair process.
