Option (A), Morton neuroma manifests as swelling of the third branch of the median plantar nerve, resulting in sharp pain in the ball of the foot, with possible stinging or numbness in the toes.
Step-by-step explanation:
Morton neuroma is a condition that affects the foot, and the correct clinical manifestation of Morton neuroma is A. Swelling of the third (lateral) branch of the median plantar nerve. This condition is characterized by thickening of the tissue around one of the nerves leading to the toes, which can cause a sharp, burning pain in the ball of the foot.
The toes may also sting or feel numb. High-heeled or tight-fitting shoes are reported to contribute to the development of Morton neuroma by putting extra pressure on the toes and the balls of the feet.
