Bunions: Bunions are bony deformities at the base of the big (hallux valgus deformity) or little toe (tailor's bunion). A bunion may be caused by hereditary factors, ballet dancing, and pointy high-heeled shoes that put pressure on the base of the big toe. Symptoms and signs include swelling, pain, tenderness, inflammation, numbness, or tingling. Treatment may involve cold applications, antiinflammatories, a change of footwear, a cortisone injection, or a bunionectomy.
