I'm not sure when it started, but it was a while ago. I think it might have something to do with me sitting down too long, but I'm not really sure. There's not a totally specific pattern.
Randomly my shoulders start to hurt. Well, it's my right shoulder most of the time. I'm not even sure if you would consider it my shoulder, actually. It's not on my neck, but it's right before your shoulder flattens out, if that makes sense...Around where the Trapezius muscle is, almost...
If I press on it enough and mess with it, a lot of the time the pain will go away. But until it does, it hurts to raise my arm above my head, turn my head...Stuff like that.
