I have hurt myself doing BodyPump, which is weight-lifting to aerobics. The pain is in the left side of my neck, trapezius area, and I noticed that I also had a knot under that shoulder blade (so it may be referred pain). Basically, it feels like a very painful knot that I can't seem to work out. I did this last week, and it took four days of all the treatment I could figure out to do (ice/advil/heat after a while/gentle stretches - on both the neck area and the shoulder once I located the lower knot) before I was sort of back to normal.
And now I've done it again.

I think this may be happening during squats, but it may be shoulders. Any thoughts? I love the class, but don't like this side effect at all!
