For the past week - week and a half I've had this tightness in one specific location of my back. It's just very stiff - feels like a muscle cramp. It's located on the right side of my back just under where my shoulder blade would sit, near my backbone. It doesn't hurt chronically, but it makes breathing difficult when riding when I'm inhaling rather deeply.

No amount of stretching or massaging gets rid of it.

Anyone ever experienced this or have a solution? I think I'm going to contact my Doctor about it, but I figured it would eventually go away, but it just hasn't yet.
