A 22 year old male with a two year history of low back pain and intermittent right leg pain sustained an acute worsening of his right leg pain 12 days prior to evaluation. He proportionalized his pain to 5% back and 95% leg pain. He complained of a new onset of weakness, tingling, and constant numbness. The pain and numbness radiated down the posterolateral leg to the dorsum of the right foot. He was unable to bear weight on the right leg and was using a walking pole for support. He was unable to sleep supine and had to sleep in a recliner to minimize the pain. Sitting provided some relief. He denied bowel or bladder incontinence, but had constipation for the last 12 days.
