Paresthesia refers to sensations such as tingling, prickling, or a "pins and needles" feeling. Given the context of poliovirus and the symptoms typically associated with it, the complaint that would most likely accompany the symptom of paresthesia is:
I feel pins and needles in my legs.
This choice directly relates to the definition of paresthesia, which captures the sensation itself. The other options either describe motor impairment or lack of feeling entirely, which would be more related to paralysis or loss of sensation rather than paresthesia.
