Pain is complex (refer to articles posted on this board). The main cause of your lower back is probably your lumbar erectors spasming due to you lifting incorrectly (causing your disc protrusion). The best way to fix this is to lift BUT with good form.
I remember your previous squat videos. You had no control over your lower back, which probably caused your disc to slip. So, keep squatting, posting vids to the board, get a coach etc. The main thing is, getting stronger will more than likely completely resolve your back pain and have you feeling healthier than before.
