Could anyone please explain the below MRI lumbar spine report ..?

Shiva, the report states this. The first part states that you have a "mild" push back of the fluid material in the disc. In the area that is stated it means that this fluid has pushed the walls of the disc outward. This movement is called a protrusion. It is fairly common and doesn't in and of itself mean anything. The question is does it match up to your symptoms? The second part states a sequestrated disc material in the right paracentral location of L4-5. These numbers are locations for the discs. What it is stating is that material from the disc has leaked out, meaning that the disc wall has been broken, but the good news is that this material will eventually dry up and be absorbed. This material is located on the right side of the spine. I would suggest that if you are having symptoms you try this. Sit in a straight chair and place your hands on your stomach. Now twist your body as far to the left as possible noting the endpoint then do the same to the right. You are going to find that one direction rotated further so start in that direction. Twist as hard and far in that direction as possible for 30 seconds then rest for 15 seconds. Repeat this twice more then do the same 3 movements to the opposite direction. Now straighten out your left leg and raise it up as high as you can noting the height achieved. Relax the leg and do the same with the right. Again one leg will go up higher so start with that leg. Raise that leg up as high as you can and then lower it. Do this 10 times and rest for 1 minute. Repeat that cycle twice more then do the opposite leg exactly the same way 3 times. Do these movements a few times a day and the symptoms should clear. Hope this helps.
