Only Sensory Symptoms III

A 30-year-old woman with a history of fibromyalgia presented with a 2-day history of pins and needles and numbness in both feet. She described the sensation as if she had slept awkwardly and compressed her feet and they now feel “dead”. By day three, the sensation had spread up her legs, affecting the left leg much more than the right and also affecting her saddle area (reduced sensation). Gradually, the sensation changed to an unpleasant, “overtly sensitive feeling” on touch, and she experienced pain. At this point, she was also having difficulty walking, with poor balance. Blood tests were normal, and she tested negative for HIV. Her thyroid function, hematinics (folate, B12), HbA1C and electrolytes (Calcium, Magnesium, and Phosphate) were normal.
