Back pain
Back pain (also known as "dorsopathy") is pain felt in the human back that may come from the spine, muscles, nerves, or other structures in the back. It may radiate from the lower, mid or upper back. The pain may be a tingling or burning sensation, a dull aching, or sharp pain. Weakness may also be felt in the legs or feet.
