Falling Risk could also just be because of weakness due to poor nutrition, for what that's worth.

I forget where you guys are located ... but is it possible the weather is a factor? We're down in Alabama (the upper part), and even though we haven't had a drop of rain yet, that darn hurricane is frying my brain with migraines. I'd forgotten how BAD this season can get. And since this is all head/neck treatment ... it might be more susceptible to the barometric pressure stuff. Long shot, but you never know. It's my worst trigger.
