When I was a teenager (and before all answers to everything were online), I went to multiple docs and no one was aware of a particular prescription that, once I found out about it, completely "cured" the issue (Drysol).
Looking back, it was obvious the doctors just weren't aware of a valid treatment for the issue. It'd be great if a service like this helps doctors discover treatments for less than common conditions.
Side note: I recently discovered iontophoresis for the treatment of hyperhydrosis without the use of drugs at all... discovered via a Facebook ad for the machine (don't ask me how Facebook knew to target me for such a specific product). I bought it a couple months ago, and wow - it works. I've been googling the studies around it, which date back to 1950's -- not something new, but also dumbfounded as to how I wasn't aware of this treatment sooner, and why no doctor was aware of it either (or at least didn't bother mentioning it as an option).
Best of luck to you! Lots of problems to be solved in the health space.
