Somewhere along my neck and traps, theres this sore/small nerve pain. when i turned my neck to the left the pain increases. (but still bearable).

This started to happen when I started doing shrugs.

am i doing something wrong?

More than likely you did something wrong. 99% sure.

i move my head foward a little? is that wrong?

you strained a cervical extensor. rest for a week and maintain ROM with light, gentle movements
