I did not know about the gout thing either. It must be something that occurs after you get diagnosed because I have had an episode of gout in my big toe that hurt like a sum' bitch.
Of course it's almost impossible to prove that something NEVER happens, the mutual exclusivity between gout and MS is only something I've heard on this site.
I don't personally know of anyone with MS and gout but I'm not aware of any research neurologist saying that the two are mutually exclusive.

Your situation is the best evidence I've seen so far.
It's FAR more certain that the MS process starts LONG before diagnosis than the certainty that gout and MS are mutually exclusive. You didn't mention how long before you were diagnosed that you had gout but I'd have to guess that if it was after your teens, you had MS at the same time you had gout. MS and gout might be a rare combination but it seems they aren't mutually exclusive.
Good question but Certain is a strong word and there are few things in life that are certain, much less the world of MS research. "Highly likely" might be a better term, but even then the highly likely factors involves opinion.
I'm not 100% sure what you mean by "true regarding the occurrence of MS" but I'd add the increased permeability of the blood, brain barrier, lesions (by our definition MS isn't truly MS until diagnosed and for that, lesions are a requirement), inflammation...maybe more than an "autoimmune" disease, MS is an inflammatory disease. Myelin loss, axon death and brain atrophy....which is all kind of the same thing.
I'm the hygiene hypothesis guy so there are other things I consider highly likely, closer to certain than anything else in the world of MS research, but they aren't commonly held views so I'm not adding them
