A bunion is a bony bump that forms at the base of the big toe, where it meets the foot. This condition occurs when the big toe pushes against the next toe, causing the joint to stick out. Bunions can be painful and may lead to difficulty in walking or wearing shoes. Several factors can contribute to the development of bunions, including genetics, foot structure, and wearing tight or ill-fitting shoes. Treatment options range from changing footwear to surgical procedures in severe cases. Maintaining proper foot health is essential to prevent bunions and other related issues.
