No, it just showed up one day. And I wouldn't classify it as a cure, at least not yet. I'd say more like an almost-complete remission. There are still days that it manifests, but not to the degree that it was. I'd say it's much, much better, but not gone. There were only two things that I can think of that could even remotely be tied to it, but even these have no real direct connection. One is having had very hot soup the day before, but I've had that in the past and since with no onset of BMS. The other is having a particular gene trigger which has, since adolescence, manifested in multiple, disparate autoimmune-type symptoms.
