  https://www.drugs.com/health-guide/corns-and-calluses.html

  Corns and calluses are a thickening of the outer layer of skin. This thickening is known medically as hyperkeratosis. Corns and calluses develop as part of the skin’s normal defense against prolonged rubbing, pressure and other forms of local irritation. […] On the feet, a small corn or callus may not cause any symptoms. However, a large, bulky corn or callus can cause foot pain and difficulty walking. […] After prolonged irritation, a discolored area (brown, red or black) may develop under a large corn or callus.

In severe cases, the thick and normal skin may separate, exposing the area to possible infection, especially in people with diabetes. […] Corns and calluses can be long-term problems if you consistently wear shoes that do not fit properly. Even with good footwear, you may continue to have painful corns and calluses if there is some abnormality in your gait or foot structure that causes unusual stress on parts of your feet when you walk.

• #9 Painful Callus Between Your Little Toes Got You Down? | Foot and Ankle Associates of North Texas, LLP

  https://www.faant.com/blog/painful-callus-between-your-little-toes-got-you-down-.cfm

  That painful callus is called a heloma molle which literally means soft corn. Heloma Molles form between toes because of the close proximity of bony prominences of adjacent toes. Pressure can begin after arthritis, a healed toe fracture, or when contracted toes from over time. Wearing tight shoe gear can exacerbate pressure between the toes leading to painful corn formation as well. The clinical picture of a heloma molle is thick yellow corn usually on the inside of the 5th toe but often on the outside border of the 4th toe as well. As the callous builds it can cause pain and can possibly become infected if left untreated. In the cases of chronic heloma molle formation with severe pain or infection, surgical correction is recommended. This is a chronic condition caused by increased pressure of bones that are not changed by conservative therapy.

  https://patient.info/foot-care/corns-and-calluses

  Corns and calluses are more likely to develop if you have very prominent bony toes, thin skin, or any deformities of the toes or feet which cause the skin to rub more easily inside shoes. […] If you develop a painful corn or callus it is best to obtain expert advice from a person qualified to diagnose and treat foot disorders (a podiatrist – previously called a chiropodist). […] Treatments such as corn plasters (corn pads) will reduce the pressure on your corn but will not actually treat the corn. […] Occasionally corns or calluses can become infected. If this happens then your corn would become more painful and the skin around the corn (or callus) will become red and sore. Pus may come out of the corn.
