The roots of corns are generally conical, with large and small heads, small ones similar to the size of a pinhead and large ones similar to the size of a soybean, about a few millimeters long, white and translucent, with a soft and hard texture. Corns are generally caused by local mechanical stimulation for a long time, such as extrusion and friction, resulting in the thickening of the keratin layer and the formation of bumps with clear borders and smooth surfaces. After removing the keratin layer, conical roots of corns, or corns plugs, will appear. The keratin plugs are about a few millimeters long, white and translucent, hard in texture, deep under the skin, surrounded by a transparent ring, and appear yellow or yellowish. The corns root is usually the root cause of the pain. When walking or standing, the corns are compressed, which can cause the corns root to penetrate deep into the subcutaneous area and stimulate the nerve endings to produce pain. When treating corns, the roots need to be removed in order to achieve a complete cure for corns. The self-healing properties of corns are low and recurring. When corns are found to form, you need to carry out relevant treatment according to your personal situation and your doctor’s diagnosis to avoid aggravation of the condition, which may affect your walking function later. If thickening of the cuticle is found, you can soak your feet in hot water to soften the cuticle and rub the affected area with a towel or pumice stone to relieve the hardening of the cuticle. Attention should be paid to avoid wearing hard shoes to reduce the friction on the foot and reduce the formation of corns.
