I agree that poisonous chemicals could cause MS. A few years ago there was a study posted here (very extensive study) saying that MS could be from more than one cause, i.e. two of these being auto-immune disease and chemical effects. This has not been studied enough, though. Or if studied, the information doesn't get out there where we see it often.

Anyway, no info from you, Annesse, on what to do. In Porphyria our main defense is avoidance. Avoid triggers of all kinds as much as possible--pesticides, herbicides, some foods, many drugs, composite furniture, new rug, rug cleaner, formalin in new clothes, on and on.
