Corns and blisters are spots on the skin that are thickened due to constant pressure. Corns are small and develop on the toes; blisters are larger and usually occur on the bottom of the foot. Pressure on both of them causes sensitivity to the tissue below them.
Corns and blisters often occur after wearing new or uncomfortable shoes. Blister may develop if you wear shoes with high heels, as this will increase the pressure on the tab pad. Some people have less coated tissue between the bones and the skin of their feet, which means that corns and blisters are easier to develop in those people.
Blisters can develop on the fingers of the hands and on the palm, especially if you are dealing with heavy manual work.
Corns and blisters are very common; almost everyone gets it sooner or later. However, they rarely become so painful to require a visit to a doctor. Among those who still go to the doctor due to problems, the ratio between men and women is 3 : 2.
Corns and blisters are usually completely harmless. However, if you have diabetes and the sensation in the feet is weaker due to sickness, deep ulcers could develop under blisters.
Self-help: wear more comfortable shoes. After a couple of weeks, corns or blisters should disappear. In the meantime, to ease any possible problems, regularly soften the hard skin with the solvent (which is sold without a prescription) and then carefully cut off the upper layers of the corn or the blister with a sharp object you have acquired for that purpose. If these self-help measures do not help, contact your doctor.
Professional help: a doctor will usually send you a pedicurist who will, with special methods, cut off surface parts of the corns or blisters and cover them with a special tool or bandage.
