Accidentally discovered, or at least it seems like it, a novel treatment for an uncommon disorder..
Very close family members' case. Many readings and analyses done along with gathering professional opinions during physicians check-ups.

Author is certain about treatment success, because even if the final outcome would be less positive than expected
it would still be far more helpful than the only approach known in the medical market at this moment.

The idea requires taking advantage of FDA-approved components available now or in 2-3 years timespan.

Lets say that an idea is interesting and worth checking.
Hearing a professional opinion is highly demanded.
Author isn't sure if commissions of physicians/scientists deal with such unique discoveries.

Question:
1. What path of idea development can you recommend?
2. Is there a way for a regular human being to request medical agency, such as FDA to at least review the approach?

Any useful assistance highly appreciated!
Words of criticism, also, but laughing is something an author would rather skip.. sensitivity is the key.

Write a paper and submit it to a respected medical journal.

I don't believe that is what the FDA does.  Their job is to review developed drugs for safety and efficacy.
