bunion area of foot
A bunion is a bony bump that forms on the joint at the base of the big toe, specifically on the medial aspect of the foot, which is the side closest to the midline of the body. A bunion is caused by a misalignment of the bones in the foot, where the big toe pushes against the other toes, causing the joint to protrude outward and the surrounding tissue, including the skin, to become inflamed and painful. The bunion area of the foot is the metatarsophalangeal (MTP) joint, which is the joint where the big toe connects to the foot.
As the condition progresses, the big toe may also begin to angle toward the other toes, a condition called hallux valgus. The bunion can cause pain and discomfort, making it difficult to walk or wear shoes, and can also lead to other foot problems such as hammertoes and calluses. Treatment options for bunions include wearing comfortable shoes, orthotics, physical therapy and in severe cases surgery.
