All my ailments are mental. Sometimes they can be a real pain in the ass, but I've learned different tools through the years to help me.
I do have one wrist thats deformed though, or the bone in my right forearm is whats deformed. You wouldnt be able to tell just by looking at it, but im unable to rotate my right hand to where the palm of my hand is facing the ceiling. I can only rotate it halfway like a thumbs up position. It doesnt take a big toll on my life, but the only thing i do with my right hand is write. My left hand is dominant in everything else lol.
I also have a torn Labrum i think its called? In my shoulder. Its the muscle that holds the ball joint of your shoulder in its socket, but mine was torn and it makes my left shoulder slip out of place pretty easily. Only in certain positions though.
