Dang lower back

I went on a road trip this weekend and my back tightened up a lot. I can't feel a lot of the things that I've been developing lately. my back is so tied up I can't get it to release. did some training last night and I'm just getting to where I can release the lower back a little bit to be able to feel the ming men point, but it feels like a knotted up mess. Lol. train train train
