A bunion is an enlargement of the joint at the base of the big toe that forms when the toe bone moves out of place, forcing the toe to bend towards the others and causing a painful bump. Bunions are caused by years of abnormal motion and pressure over the big toe joint from factors like inherited foot type, poorly fitting shoes, and how we walk. Symptoms include a swollen bump at the base of the big toe and pain with movement. Treatment options depend on the severity but may include padding, orthotics, physical therapy, anti-inflammatory drugs, and surgery to remove the bony enlargement and realign the toe joint.
