Upper/mid back pain?

lola0915

Is anyone else getting this muscle cramp or knot feeling in their back? I have one spot on my right side below my shoulder blade that feels like a knife is stabbing me. It only happens when I'm sitting which makes sitting in a car ridiculously painful. 

I hope to go home for Thanksgiving and it's a 3 hour drive. Does anyone have ideas to relieve this pain? I've only had one massage and that didn't help but maybe I need more.
