Mild, moderate, or severe back pain, particularly in the upright position, is the main complaint. Lying down may relieve some of the discomfort. In most cases, the discomfort lessens a great deal within 6 to 8 weeks.
If several vertebrae are compressed, a rounded or hunched back may be noticed. Rarely, the compression fracture may be severe enough to cause pressure on the spinal cord or nerves. If this occurs, it could result in numbness, weakness, or paralysis of the legs, bladder, or bowels.
Other signs include tenderness over the compressed vertebra and spasm of the muscles around it. Standing with an erect posture may be hard.
