Nerve pain. A bulging disc can slip out of place and irritate the surrounding nerves. It results in weakness, numbness or pain in the arm or leg. The spinal canal tends to have limited space. It is not enough room for a bulging disc and spinal nerves. This results in the disc pressing on the spinal nerves, which can produce extreme pain. It is common for sciatica to occur from a bulging disc. This condition puts pressure on several nerves that contribute to the sciatic nerve. The additional pressure may cause someone with a bulging disc to experience burning, tingling and numbness that radiates through the leg. These things are why someone with bulging disc experience nerve pain.
