Every now and then I'll feel a small pinch while working out in the upper middle area if my spine or slightly left or right of it. It usually doesn't hurt so much that it interrupts me from finishing the workout but afterwards it causes my back to tighten up and hurt for a few days. Usually lasts 3-5 days.
Whenever this happens it's usually during something simple. For instance it happened Sunday during my freakin warmup. I stepped under the unloaded squat bar and when I got into position I felt a pinch.
Activity usually makes the pain go away, for instance I woke up stuff and in some pain this morning, stretched and played ice hockey and didn't feel a thing until after my nap. I just woke up for work and was tight again.
It's the kind of pain that you feel it when you lower your chin to your chest. I'd like to know what it is exactly, muscle pull or a nerve or whatever. And If there's something I can do to prevent it. It's annoying because I don't want to miss any workouts.
