Middle back pain can indicate anything from minor muscle strains to spinal fractures, according to WebMD. The severity and persistence of the pain can help indicate how severe it is, as can the presence of any trauma or other possible causes.
Most middle back pain is fairly mild and is caused by muscle strain, explains WebMD. Poor posture, lifting heavy objects incorrectly and other routine actions can cause it. This type of pain usually goes away after a few weeks if the cause is removed, but it may persist if the person continues to strain the muscles. Patients with osteoarthritis in the spine may also experience middle back pain. Herniated discs can cause the condition by putting pressure on the nerves. Trauma, such as falls or car accidents, can damage the spine or muscles and lead to middle back pain.
Although most causes of middle back pain are a result of injury to the bone or muscle, some diseases can cause the condition, such as cancer or gallbladder disease, notes WebMD. Certain infections may also be a cause. However, these are rare. Most cases of middle back pain can be treated at home. Rest, ice, mild exercise and over-the-counter anti-inflammatory drugs can often cure it. Sudden or severe back pain, or pain that persists for more than a few weeks, should be treated by a doctor. It is also a good idea to visit a doctor after experiencing any serious trauma that causes pain.
