The foot is compared to the second heart of the human body, because it is closely related to many body organs. Many diseases of our body are manifested in the feet. For example, 80% of patients with rheumatoid arthritis will have foot deformity; patients with long-term diabetes may cause foot ulceration; patients with gouty arthritis, toe swelling and pain are often the earliest manifestations. However, many children don’t care much about foot health, so they ignore the health warning from foot. Today, experts from the Health Education Institute of Beijing CDC come to talk with you about how to take good care of our feet.
How important are our feet? According to reports, the foot structure is very complex, each foot has 27 bones, 33 joints, more than 100 ligaments and tendons, these joints, bones and ligaments muscle joint action, coordinate movement, help the human body to complete a series of complex functions. In the process of walking, running and jumping, our feet bear five to six times the weight of the human body. Every step, our legs and feet have a process of muscle contraction and relaxation, which will help promote the blood circulation of the limbs. Therefore, it is very important for us to have a pair of healthy feet.
Foot diseases can occur at any age. For example, children’s common congenital foot diseases; teenagers in addition to congenital foot diseases, there may be sports injuries; young adults, in addition to accidental injuries such as sprain, fractures, there may be sports injuries or arthritis after injury; elderly common foot degenerative changes. The structure of the arch of the foot helps us to finish running and jumping, which is very important. If the arch of the foot collapses, the joints, ligaments and muscles will not function well. Some movements and postures can often only be maintained by a single joint and ligament, which is easy to break and the joint is prone to arthritis. Arthritis and ligament fatigue, injury, are the manifestations of foot degeneration.
What are the common foot problems? Here’s what our feet are likely to face most often.
Reddening of skin: reddening of the protrusion of the little toe and the big toe bone, but no pain, indicating that the foot may be relaxed and widened. The shoes we used to be able to wear may squeeze our feet now. The first thing we squeeze is the protruding part of the bone. If we squeeze too much, there may be pain.
If you insist on wearing shoes that squeeze your feet, the skin on the rubbed part may be ulcerated or secondary infection, or even the infection may deepen, leading to osteomyelitis. Patients with diabetes should pay special attention.
Callose: commonly known as cocoon, it is a large keratinization. There are few young people, but there are often old people. Because the elderly foot comprehensive coordination load-bearing structure becomes uncoordinated, the local foot bone load increases, the human body out of self-protection, the local skin will generate a thick keratinized layer to protect the skin.
Corns: like the eyes of a chicken, corns have deep keratinization in the middle, which often appear in the protruding parts under stress. The most common cause is the growth of age, small bone formation of bone hyperplasia, and then combined with external pressure, constantly friction toe skin, resulting in corns.
Wart: wart is a kind of protuberance on the skin caused by virus infection, commonly known as scrofula. Wart has three characteristics: a large number; not necessarily long in the foot bone; infectious.
Ingrown toenails: toenails that grow into the flesh can be very painful and easily infected. After ingrown nail, some people can appear paronychia.
Blisters: when walking too much, blisters may appear on the skin of the feet, causing skin damage.
How to carry on the foot’s daily inspection? Experts from the Institute of health education put forward three suggestions.
Scratch the skin with a cotton swab: scratch the skin with a soft cotton swab to see if you can feel it. If the feeling is not sensitive enough, it means that when the foot is injured, it has no pain or does not have enough pain to make the human body notice that the foot is injured, so it is unable to take protective measures in time.
Check the heel: most of the normal degenerative heel is shorter. If the heel is short, the front of the foot will bear more strength than the heel when walking, and the cocoon and pain of the front of the foot will appear more easily. We can try to hold the railing, stand on the steps, and put the heel down. Some people can put it down, some people can’t put it down, and some people will have pain, that is, the Achilles tendon in the heel will have pain. The latter two cases show that the Achilles tendon is short or abnormal.
Regularly check the condition of the feet: regularly observe the changes of the color and width of the feet, whether the toenails are thicker, whether the skin is damaged, and whether the size of the feet has changed. Pay attention to wipe the toe space after washing feet. When cutting toenails, pay attention not to cut too deep, so as not to damage the skin, especially in patients with diabetes.
In addition, experts especially suggest that in daily health care, don’t ignore the problem of foot pain. If the foot pain lasts for more than three days, be sure to go to the hospital for examination. (our reporter Li Jie)
