Here is My Question:
Can you please explain what symptoms might be associated with a T9 spinal lesion? I currently have reduced sensation/numbness on one side (R) of my lower back, wrapping around my lower abdomen and down the front of my R leg. Some back and hip pain on R side as well. Thank you.
You've done a great job describing the symptoms associated with a partial right sided demyelinating lesion at the T9 level.
Sensory nerves carrying pain sensitive axons from the T9-T12 or even the L1 right sided dermatomes (depending on the length of the lesion in the cord) enter the spinal cord in this area and cross over to the opposite side of the spinal cord about 2 levels above their entry zone. These dermatomes (T9-L1) correspond to the region of numbness you describe on the right side of your trunk and the front of your right leg. From here they travel up the left side of the spinal cord in the spinothalamic tract.
Common symptoms include a tight squeezing sensation around the trunk, sensitivity to light touch or pressure and a burning or tingling sensation. Other possible symptoms really depend on the location of the region of demyelination and could include weakness in one leg, tingling in one or both feet, urinary urgency or retention, constipation, lack of sensation in your private parts or decreased balance.
