Abnormal Nerve Conduction test

I recently had a nerve test done and the results came back abnormal.  Here is the basic info: I am a 46 y.o. female, symptoms include numbing sensation from just above right knee down to about mid calf, as well as some pain and occaisionally a heat sensation.  Went to orthopedic dr, and he discovered on examination that I had little to no reflex in that leg.  NCV test results were as follows: "Decrease in sensory amplitude recorded in left sural nerve.  Increase in sensory distal latency in right sural nerve. Decrease in motor amplitude recorded in right tibial nerve.  Motor distal latencies within normal limits.  F-wave latencies within normal limits."  I am scheduled to have an MRI of the lumbar this week.

Hi there. Abnormal NCV test results could be due to some nerve damage or destruction, axonopathy or damage to long portion of the nerve cell, conduction block or demyelination. These could be seen in various conditions like diabetic neuropathy, uremia, traumatic injury to nerves, Guillain Barre Syndrome, any peripheral neuropathy, damage to spinal cord and disc herniation with nerve root compression. Consult your neurologist and wait for the MRI to reveal more about your existing pathology. Hope this helps. Take care.

I got the mri results today.  The doctors office didn't seem to be to concerned, but the results are as follows: "A hemangioma is noted in the T11 vertebral body.  T12-L1 small central disc extrusion without compression of the conus.  L3-4 small right foraminal / far lateral disc protrusion without nerve root compression.  L4-5 minimal disc bulging and facet hypertrophy.  L5-S1 small central disc protrusion without nerve root compression, mild facet hypertrophy."  The good news is no nerve root compression.  The hemangioma was an incidental finding.  Is it unusual to have multiple prodtruding discs with no injury or trauma?  And should I have the hemangioma further evaluated?
