hey man, i got blown up and compressed 3 of my verts and it laid me up pretty bad for a very long time. no inj or sugery but i did exactly what they told me for almost 2 years with pt and all the other crap. what i figured out after stopping listening to those clowns was this. i finished off every single workout with hypers. 5-6 sets of 10. sometimes i would have to lay on the floor after before i could leave but over a few months it strengthened the area up enough where i was able to start doing heavy deads and squats again with no issues at all. i still tweak it from time to time but it is very managable for me now. i also did some traction work with the chiro that helped a lot also and i always were a belt when doing any deads or squats over 315. stretch those hammies also. that could also be a source of trouble that they arent looking at.
