25.關於 referred pain 和 radicular pain 的敘述，何者有誤?
(A) Radicular pain is lancinating in quality, like an electric shock, and travels into the lower limb along a narrow band
(B) Somatic referred pain is perceived as a dull, aching sensation； it radiates slowly over relatively wide areas
(C) The causes of somatic referred pain and radicular pain are quite different, and their mechanisms are different
(D) The mechanism of radicular pain is irritation of the dorsal root ganglion of a spinal nerve
(E) This is correct that somatic referred pain does not extend below the knee and that, therefore, pain below the knee must be radicular in origin.
