Oh I forgot to ask about your posture???
esp upper body, but the whole is an important thing to be aware of also.

shoulders hunched or rolled forward?
head forward of the body?
one shoulder higher, lower or tilted- same with hips

I have tilted/uneven shoulder, hips, ribcage - I remember when I started wearing 2 pc swimsuits as a kid- my ribs weren't even then.
not obvious to everyone but to me it was.
I may have had this tilted thing since birth..
I was also a tomboy and played backyard sports, rode horse, motorcycles, jumped out of trees and off roofs- so all those probably aggravated any minor spine things.
Landed on my head one time @ age 15 - mild concussion.

Then turning 40 and doing repetitive work for 10 hr days for many yrs - not a good thing.
