A bulging disc can put pressure on the nerve roots coming out from the spine, resulting in middle back pain. In addition, a problem in another part of the body, such as the heart or digestive organs, can radiate to the middle back. This is called referred middle back pain.
A sudden injury to your back, such as from a fall or a car accident, may also start this process. This problem can occur anywhere on your spine. But in most cases, it occurs in the discs in the lower back and neck. In rare cases, upper and middle back pain may be caused by other problems, such as gallbladder disease, cancer, or an infection.
