Waking up and feeling very numb on lower left side of abdomen.. lasts for a long time but not painful.. what can this be?

Asked MD?: This is an odd symptom. Does "numb" mean less feeling or too much feeling, i.e. Paresthesias (pins and needles)? Are there skin changes over the area (as in old shingles)? The nerves supplying the left lower quadrant come from the lower thoracic spinal roots, i.e. From the spinal roots at the lower end of the rib-cage. How long is "a long time"? Has your doctor examined you? What does (s)he say?
