Hello,
New here and I must have messed up when I replied the first time, becuase it never showed up.

I also have bulging discs in L1/L2, L4/L5, L5,S1. Best thing that worked for me in Therapy was traction, where they strech you for a 15 minute session 2 or 3 times a week. You'll notice a little improvement the first day, but after a few weeks you can really notice if it works for you. I had it done for about 4 weeks and then was given some other exercises to do to help support it and it helped for about 6 months. Hope this helps a little.
Take care,
Dennis
