Plantar fasciitis (heel spur) can often be confused with tarsal tunnel syndrome, which arises from the compression of nerves leading to the sole of the foot. There are distinct symptomatic differences that aid in the differential diagnosis of these two conditions. In plantar fasciitis, numbness is not observed in the sole of the foot, and pain is generally limited to the heel region. In contrast, in tarsal tunnel syndrome, numbness is felt throughout the entire sole of the foot, while pain can extend from the sole to the tips of the toes. Another common symptom of tarsal tunnel syndrome is a burning sensation in the sole of the foot.
