I concur and also recommend! 

I got a big foam roller noodle thing from 5 below, rolling my mid to upper back and it feels sooo good (a little painful at first because muscles are so tight)

My IT computer slouch pain is so much better. I do it every other day for 5 minutes now. 

I also use it on my calves-but no matter how much I do them they still hurt. I don't even think there's anything in my calves other than knots. But the frequency of my leg cramps has significantly reduced when all the supplements didn't.

Also tennis ball on the wall for those weird knots next to/underneath the shoulder blades that the roller doesn't get deep enough.
