When I started my first job where I did a lot of coding, I noticed that I would wake up at night with a bit of in my left hand occasionally (pinky especially).

When I started my first job where I did a lot of coding, I noticed that I would wake up at night with a bit of in my left hand occasionally (pinky especially). I also noticed that when I walked I started to feel the nerves "move" if I jostled about, very odd feelings. I adjusted my work environment with a close eye to my posture, got a new ergo keyboard, changed out the chair. Within a few days all the pains and aches had left. TL;DR Change it up, then go see a doc if nothing helps.
