Transverse Myelitis is an inflammatory disorder caused by damage to the spinal cord. When this damage occurs, nerve communication along the spinal cord to the rest of the body is interrupted. The location of damage on the spinal cord determines which part of the body does not receive nerve signals, causing a loss of sensation and muscle function to that area. The cause of this condition is not always known. However, several conditions are known to cause transverse myelitis such as infection and immune system disorders, as well as some inflammatory or vascular disorders. The four classic signs of TM are (1) weakness of the legs and/or arms, (2) lower back pain or sensation that radiates down the limbs or around the torso, (3) sensory issues (such numbness, tingling, coldness), and (4) bowel and/or bladder dysfunction.
