There are various growths that could affect your feet and toes, including blisters, bunions, corns and calluses, heel spurs, warts, and neuromas. Blisters are pockets of fluid-filled skin that typically form when there is friction or rubbing. A bunion is a deformity caused by a misaligned big toe joint.
Corns and calluses are thickened areas of skin where there is pressure and friction. Heel spurs are growths found underneath the heel bone. Neuromas are a common nerve problem that causes shooting pain between your toes. Warts are caused by a viral skin infection and spread from person to person.
