Pain, numbness, and tingling can be from nerve related issues. The spine is composed of bone (vertebrae), support ligaments, intervertebral discs, surrounding muscles, and nervous tissue. Because of the design of the spine, the close proximity of bone and disc to nerve tissue, pressure on the nerves from discs or other tissues may cause pain. The nerves are very pain sensitive structures and any pressure throughout the length of the nerve may cause pain. Another source for creating these symptoms into the arm could be from any muscle, usually in spasm, pinching the nerve as it travels down the arm.
