Hi Amando,
I am sorry to hear about your back problem.
I am not a doctor and this isn't medical advice, but I know lots of people, including myself, who have had problems with bulging discs. For me, it was from playing a lot of guard, then not stretching in the opposite direction afterwards to ensure balance. (Doing cobra stretches).

I have been fine through being sure that I balance the direction of the pressure on the spine. I also am sure to massage the area around the lumbar/sacrum by laying on a hard lacrosse ball nearly every night.
Tuhon Inosanto had a terrible problem with his back years ago. Now, it is all strengthened through yoga and BJJ. He trains like a madman at 75 years of age.
Get your therapy, strengthen that up, and I am sure that you can get back to training.
