That's just the way the body works, it no longer produces certain chemicals and you'll know it when you advance into your twilight years; think hormones!!!!!!!!!!!!!!!!!!!!!!!!!

While both sides of the body resemble one another, there's some asymmetry going on. You know, you favor one side more than the other: handedness, left handed versus right handed yada yada yada. What do you do with your right hand that you don't do with your left hand********** HUH?!?!?!?!?

As to your xrays, please find someone local as I've been out of practice for almost twenty years.
