You go to a chiro and check if your spine is straight or not. Every problem I had including something like your problem was because one side of my spine was leaning to the left. It's ussually caused from sleeping on 1 side every night/having 1 leg shorter and 1 leg longer/sitting with wallet in your back pocket causing a one sided lean.

This one sided lean will normally cause the muscles in 1 side of your back to become stiff due to the pull. E.g if your spine is leaning to the left your right back muscles will feel fck'ing tight.

Sleeping completely straight on the floor on a yoga mat for 1 month solved it for me. You can check my log regarding this.
