Yes sir, I have experienced a similar injury, and I really can sympathize. It’s very painful, and if you’re anything like me, you are probably wondering if you will ever be able to deadlift again.
The good news is yes, you will. I bulged my L-4 and L-5 while doing deadlifts about five years ago. (I got sloppy with form while bringing the weight back to the floor.) I still deadlift, squat, power clean, power snatch, etc. to this day, so don’t worry.
That being said, you must take things SLOWLY. I found that a good chiropractor, along with proper physical therapy, helped dramatically. Be advised, though, that a lot of doctors will advise you to stop deadlifting.
Being stubborn, I declined that option. You are going to have to lay off D/L’s for about zix to eight weeks. When you do start again, go light. Concentrate on form, and over time, increase the reps. Light sets of ten reps are going to do more for your body repair-wise than going heavy right away.
Make sure you warm the area up with some hyperextensions and reverse hypers performed with no weight, at first.
After another month or two, you can probably start working your way to putting more weight on the bar.
If at any time, you feel that same pain that you felt when you first hurt your back, STOP RIGHT THERE. Put the weight down and leave the gym. DO NOT try to finish your workout. Go see your chiropractor immediately.
The key to coming back from this injury is leaving your ego at the door for the first few months, and doing what is best for your body. Leave the big numbers for another time.
I relate these tips to you from experience, having re-injured the same site twice. Got it right the third time.
Good luck, and sorry about your back. I know it hurts like a bitch.
