Earlier today i tested on my squat max, i put on 330 and on my way down i had very bad form so on the way up i used a lot of my back and not my legs. ABout an hour later i had a very sore lower back like i pulled something. It still hurts alot now and imm kindof nervous about it because my friend just had to get back therapy because of squats. I satnd straight and touch my chin to my chest and i feel it on my back. I was wondering if this will heal naturally and if so how long. Thnx
