I am a chiropractor. Herniations of non-traumatic origin are usually due to years of poor disc nutrition, coming from severe postural imbalances in the lumbar spine or from fixated vertebrae over the long term which prevents the disc between them from receiving adequate movement and hydration. This slowly weakens the disc until the disc tissues themselves become so weak that they can no longer withstand the weights and pressures of the body. Consider finding a chiropractor who utilizes the Cox flexion-distraction disc decompresson technique. Do not let anyone offer you hard, side posture adjusting techniques, which are common. Good luck.
