A bunion is a bony bump that forms on the joint at the base of your big toe. They can develop from an inherited structural defect, excess stress on your foot, or can result from an existing medical condition.

Calluses, on the other hand, don’t usually cause pain. They usually develop on the soles of your feet, especially under the heels or balls, on your palms, or on your knees. Calluses vary in size and shape and are often larger than corns.

Corns tend to be smaller than calluses and are the hard center is surrounded by irritated skin. While corns can be found on the bottom of the foot where pressure is usually applied, it is more common that you find corns on the tops and sides of your toes and even between your toes. When pressure is applied, corns can cause significant pain and discomfort.

While most plantar warts are not a major health concern, it is advised you see a doctor to have the warts examined and removed. Some symptoms include small, rough lesions on the base of the foot, calluses in one spot, and tenderness when walking or standing for long periods of time.

Hammertoe is a deformity where one or both joints of the second, third, fourth or fifth toes begin to bend outside of their normal alignment. Pressure can begin to weigh heavy on the toes as you wear shoes which is where pain and other symptoms develop.

Heel spurs occur in at least 50% of people who have plantar fasciitis. Past treatments for heel spurs, a bony growth that begins on the front of your heel bone and points toward the arch of your foot, included surgery to remove the growth. Nowadays, surgery is rarely a treatment option and more plans for physical therapy, ice, and pain medications are used to treat heel spurs.
