Strength training/weight lifting, basic yoga stretches like sun salutation and squats/lunges to strengthen the back have helped a lot. Long uninterrupted work session still can bring back my pain, but of all the remedies/treatments I have tried the only thing that works are physical exercise focused on core/back strength.
