A 60-year-old woman with Multiple Sclerosis reports that she has been feeling a sensation of "pins and needles" in her legs. What could explain this symptom?
This patient is likely experiencing a symptom called paresthesia, which is common in Multiple Sclerosis. Paresthesias can feel like tingling, numbness, or a "pins and needles" sensation. They result from damage to the nerve pathways involved in sensory perception. Management might involve medications that help control nerve pain, such as gabapentin or pregabalin.
