![]() Corns & Calluses
What are corns and calluses? Corns and calluses are hard, thickened layers of skin tissue that build up as a response to friction and pressure your toes experience in prolonged rubbing against another surface. Variations of hard corns are soft corns, which are more like open sores that develop on skin surfaces between the toes. Although corns and calluses are similar in make-up, corns are generally small, often painful and usually found on the tops or sides of your toes. Calluses are usually larger, normally are not painful and generally are located on the soles of your feet (Calluses can also develop on your hands, usually on the palms). While corns and calluses may be less than attractive to look at, they are harmless and do not need to be treated unless they cause pain or otherwise interfere with your ability to be active.

Each of your feet has 26 bones, more than 30 muscles and numerous tendons and ligaments that work together to bear and propel your body weight during standing, walking and running. Bones provide support, ligaments provide stability and muscles and tendons provide movement. The toes (as well as the fingers) are each made up of bones called phalanges, two in the big toes and three in the others. The bones at the ends are called the distal (meaning farthest away) phalanges, the ones in the middle (not present in the big toes) are called the middle phalanges, and the ones closest to the other bones of the feet are called the proximal (or nearest) phalanges. These join directly to the metatarsal bones, which lead to the bones that make up the ankles. As you walk, the joints that connect these bones, held together by muscles, ligaments and tendons, flex each time you take a step. You place 1½ times your weight on your feet when you walk normally (and more when you run) and it's estimated that the average person walks for approximately 1,000 miles each year. (return to top) What is the make-up of corns and calluses? Corns develop when the friction of skin rubbing against a surface (such as shoe leather) over time causes the skin's surface layer to build up. While this thickened skin becomes dead tissue, the layer underneath can become irritated and painful. A typical corn will present itself as a small mound of dead skin with a painful spot in the middle. While calluses involve the build-up of skin tissue, they generally escape the irritation of the skin below. They tend to develop on less sensitive areas of skin and develop more slowly over a longer period of time. Most corns are small mounds of tissue less than a quarter-inch in diameter. Calluses tend to be larger and can vary in shape. (return to top) What causes corns and calluses? Wearing ill-fitting shoes is the number one cause of corns and calluses. The friction and irritation that leads to their development can be caused by:
Problems such as hammertoe frequently have corns associated with them, since the tops of the affected toes tend to be jammed against the tops of the shoes' toe boxes. In addition, ill-fitting socks that create irritation can lead to the development of corns. (return to top) Do I need to see a doctor about my corns and calluses? Based on their appearance, their "feel" and the pain you experience, your corns will be pretty self-evident. Your doctor can certainly confirm their nature and offer treatments for them. However, since warts and plantar warts on the soles of your feet can resemble calluses, it may be wise to consult a physician about those issues. More importantly, your doctor can help you find solutions for preventing future development of corns and calluses. And, if your corns are associated with a more serious condition such as hammertoe, you should consult a physician. If you have diabetes, it is important that you consult a physician about any foot problem, including corns and calluses, since foot issues can become serious for diabetics and self-treatment is not advised. In fact, if you have diabetes, you should consult the accompanying article on diabetic foot care. You can do so by (clicking here). (return to top) What can I do to treat corns and calluses? If you can eliminate the source of irritation, your corns and calluses often will disappear over time. Some steps you can take to assist this are:
(return to top) What treatments will a doctor provide for corns and calluses? If you have a bothersome corn or callus that won't go away with padding, rubbing or a change in shoes, you should consult your physician. During your visit, your doctor may be able to reduce the size of your corns by using a scalpel to shave layers of dead skin off them. If your corns are associated with a more serious condition such as hammertoe or bunions, he or she can help you deal with that through either medical or surgical treatment. If conservative treatments such as padding and use of orthotics don't help, Hartford Specialists' podiatrists are skilled and experienced in surgical correction of hammertoes and other problems through realignment of bones to correct a deformity and various other surgical techniques. In addition to dealing with the immediate problem of existing corns, your doctor can help you find ways to prevent future corns and calluses from developing. Among other possible methods, he or she may prescribe orthotics, inserts you can wear in your shoes to correct mechanical foot-motion problems that lead to the development of corns and calluses. If you have diabetes, it is important that you consult a physician about any foot problem, including corns and calluses, since foot issues can become serious and self-treatment is not advised. (return to top) What can I do to prevent corns and calluses from recurring? If you go back to the same habits in terms of shoes, you are likely to develop your corns and calluses again. To avoid them: Wear roomier shoes
Don't wear high-heel shoes
Wear orthotics to correct mechanical movement problems
