Hi, Thanks for writing in. There are small spongy discs between the small bones in the spine. These discs should be aligned in a normal fashion to allow various movements in the spine and also provide cushioning. In your back the discs at many levels L 3 - L 4, L 4 - L 5 and L 5 - S 1 are bulged backwards and this might be due to trauma or early degeneration. You may try doing physiotherapy and avoid lifting heavy weights. This problem will not heal completely but if you take precautions, the progress of the problem will be slow, and you will still be able to continue with your daily activities without many troubles.
