I blew outl4-5 and s1 in my early 20's while squatting, PT and just enjoy the pain for about 20 years until i had the disk trimmed. Pretty much pain free all the time, unless i sleep on the couch or some weird position. Herniated c4-6 a few years ago, unsure how. Started losing use of the arm and had them fused. Zero pain now. My left bicep is an inch smaller than my right still.
