here's something radical :

go to a chiropractor.

not a run-of-the-mill guy, but someone who's gung-ho about finding out what's going wrong.

i had a chiropractor once do for me what a doctor has never done : he showed me my x-rays. he showed me the sideways curve in my spine that no other doctors had thought to be concerned about.

the spinal chord controls the organs of your body, and when a portion of your spine is out of alignment, or damaged, then the organs regulated by the chords which exit the spinal column in those areas will be affected. this is the usual cause of mysterious afflictions of vital organs.
