every weight lifter who has lifted heavy over a long period of time has herniated or damaged discs, it comes with the territory. i have atleast 3 myself! the thing is for some of us it will bother us and for others it isn't a big deal. sitting in front of a computer does not help the situation. consider getting a stand up desk if you are an office worker
the next thing you gotta do is change how you lift. no more lifting heavy, lift light and accept that is how it will be for a while. you also should be doing hot yoga and using an inversion table daily to decompress the spine. if you keep pounding away the issue will get worse and worse to the point where you will need surgery and cortisone shots
