Causes of back pain include spine injuries, infections and tumors, medical problems such as intervertebral disc degeneration, and diseases such as scoliosis, endometriosis and arthritis, states WebMD. Chest pain can occur from heart-related causes, such as aortic dissection and angina; digestive causes, such as heartburn and swallowing disorders; and bone causes, such as sore muscles and costochondritis, notes Mayo Clinic.
Back pain is not a diagnosis but a symptom of a medical condition, reports WebMD. Improper lifting or twisting can cause spine injuries such as fractures and sprains, causing back pain. Severe injuries from falls and accidents can also cause this pain, as well as infections that involve the vertebrae, called osteomyelitis, and those involving discs that cushion the vertebrae, called discitis. Medical causes of back pain include muscle tension, spasms, wearing down of the facet joints and the deterioration of discs with age, causing them to lose their cushioning ability.
Chest pains occur from rupture of the aorta and the buildup of plaque on the inner arterial walls, narrowing the arteries and causing insufficient supply of blood to the heart, explains Mayo Clinic. Washing up of the stomach acid into the esophagus or heartburn, as well as difficulty swallowing due to disorders of the esophagus, can also cause chest pain. Other causes include inflammation of the cartilage of the rib cage, broken rib and chronic pain syndromes, such as fibromyalgia.
