Transverse myelitis is an inflammation of the spinal cord that damages the protective myelin sheath surrounding nerve fibers. It causes symptoms like pain, muscle weakness, paralysis, and problems with bladder and bowel function. The exact cause is unknown but may result from infections, immune disorders, or other medical conditions. Diagnosis involves exams and tests like MRI or spinal tap. Treatment focuses on reducing inflammation with steroids or plasma exchange and managing symptoms with pain medication, physical therapy, and nursing care like skin care and bladder management. Complications can include permanent paralysis, pain, spasms, and depression.
