What condition does Morton's neuroma primarily affect?

Morton's neuroma primarily affects the ball of the foot. This condition involves the thickening of the tissue around one of the nerves leading to the toes, which usually occurs between the third and fourth toes. This thickening can cause pain, a burning sensation, or numbness in that area, making it uncomfortable to walk or wear certain types of shoes.

The ball of the foot is where the metatarsal heads meet, and this region bears considerable weight during activities like walking or running. Hence, any neuroma in this area can lead to significant discomfort. Understanding the anatomy and mechanics of the foot helps clarify why Morton's neuroma is associated specifically with the ball rather than other parts, such as the arch or heel, which have different structural and functional properties.
