Mondo Description Cauda equina syndrome refers to a group of symptoms that occur when some of the nerves in the cauda equina (the bundle of nerves that spread out from the bottom of the spinal cord) become compressed and/or damaged. Signs and symptoms of this condition include pain, numbness, or tingling in the lower back and/or legs; ' foot drop '; problems with bowel and/or bladder control; and sexual dysfunction. Cauda equina syndrome may be caused by a herniated disk, tumor, infection, fracture, or spinal stenosis. Treatment usually targets the underlying cause of the condition and often includes surgery to remove the material that is pressing on the nerves. Physical therapy, occupational therapy, and/or other services may be required if symptoms persist following surgery.
