Nerve pain in your arm or leg or nerve pain in another part of your body has several causes. The most well-known nerve pain is a hernia in your back or neck. With a hernia the nerve root is pinched by a bulge of an intervertebral disc. All nerve entrapments that happen within the spine are called central nerve entrapments. All the nerves that gets trapped outside the spine are called zeperiferous nerve entrapments.
PERIPHERAL NERVE ENTRAPMENT
What many people don’t know is that nerve pain can also be caused by muscles that pinch nerves. Nerves run through and along muscles and tendons. In an ideal world, they glide smoothly past each other. However, due to overload, scar tissue or stiffness, the nerve can be pinched by the surrounding tissues. Often hernia complaints are actually a peripheral nerve entrapment.
