If the doctor finds anything with the cat scan (which he hopes he will) he is only going to prescribe his useless remedies which involve either drugs surgery or both.

Go ask Dr. Sutter at ask Dr. Sutter forum as a place to start.
Whatever it is can be fixed naturally and also won't very likely get fixed any other way.
Going the MD route is more than likely what is known as "hell on earth".
