A bunion is a bony, often painful hump that forms at the joint at the base of the big toe. Bunions may run in the family and sometimes develop with arthritis. Bunions may swell, turn red, feel tender to the touch or even feel painful. Overtime it may also become shiny and feel warm to the touch. If you have pain while walking in otherwise comfortable shoes, schedule an appointment with a physician at the Cleveland Foot & Ankle Clinic to develop a treatment plan.
