This means that at the very bottom of the spinal column (L5 is the last lumbar vertebral body), there is a bulging disc (the intervertebral shock absorber) that is leaning toward the right side, where the spinal nerve exits the spine on its way to the leg. Because there is also some degenerative change (arthritis) in the nearby joint, there is narrowing of the space through which the nerve exits. Sometimes this results in pressure on the nerve, with resulting pain and/or weakness, and sometimes it doesn't.

Your doctor, after taking a careful history and doing a thorough neurological exam, should be able to tell you if this finding is related to any symptoms you may be having in your back or leg. If there is any uncertainty about this, you could request nerve conduction tests (NCV/EMG) to see if there is any evidence of nerve damage in the leg, and if so how severe it is.
