A bunion — medically known as hallux valgus — is a deformity of the forefoot in which the big toe drifts towards the second toe. The first metatarsal head sticks out medially, appearing as a lump on the inner-side of the foot.
As the deformity gets worse, the big toe also rotates and slightly elevates, so that the remaining metatarsals at the base of the lesser four toes have more load and become more painful. The skin over the bunion is often red or sore, and the joint may feel painful. Movement of the big toe may also be restricted, particularly if there is arthritis in the joint.
Bunions generally develop because of a family history. Stress on your foot, particularly when wearing tight shoes with high heels, will then bring this genetic predisposition to the forefront.
