According to statistics, the average person walks 8,000 to 10,000 steps a day, which can be calculated to travel around the earth more than four times in a lifetime, and if there is a problem with the feet, it will be like a deflated tire “difficult to walk. The foot is one of the most complex structures in the human body, and the two feet are made up of 52 bones, accounting for a quarter of the number of bones in the human body. When God designed the “foot”, it was not meant for people to wear shoes or walk on concrete floors. The foot plays the role of “mobility” and “stability”, but with repeated stepping movements, the original minor physiological defects of the foot often become significant, especially after exercise or prolonged standing, minor symptoms can easily become difficult foot diseases, more often combined with lower back pain, hip pain, knee pain and other problems. Different parts of the foot will occur in different diseases, common foot problems are: 1, flat feet: the arch is like a spring can cushion the pressure. Flat feet because of the lack of arch support, the foot presents a state of internal rotation, the joints are more flabby, unable to support the weight of the body, easy to walk the whole foot hit the ground, the pressure can not be absorbed, so easy to fatigue, sprain, and can not walk fast, muscle pain and inflammation. It is recommended that shoes with arches should be worn, using insoles to reduce the pressure on the bottom of the foot and improve the symptoms. 2, bunion: women often wear thin heel, narrow shoes, in addition to the center of gravity is easy to instability, poor blood circulation, but also the big toe to both sides of the body compression, serious will be overlapping with the second toe, a slight bunion can be improved through shoes (toe shoes), foot pads, when the angle of bunion in 15 to 20 degrees or more, before considering open surgery, but if you do not pay attention to health care, there is still a possibility of bunion again, so Should try to reduce the pressure on the foot, choose shoes with large lasts, air cushions and soft heels. 3, heel pain (plantar fasciitis): “walk a step, a pain” is the best description of this type of patients, especially in the wake up or rest just after walking those few steps, simply painful. Because the plantar fascia is injured by abnormal tension and traction, excessive walking and prolonged standing should be avoided, and special attention should be paid to the fact that patients often think that stimulating the painful point is effective, so they walk healthily, which leads to the deterioration of the already inflamed fascia, and the inflammation will grow bone spurs in the heel for a long time. Shock waves can promote tissue metabolism and circulation, as well as pain relief and tissue repair, without the need for surgery and wounds, which is a new choice for patients. Simple self-examination methods, early detection of abnormalities and prevention: 1, foot calluses: excessive friction or pressure on the skin will form a callus, if there is a thick callus formation under the foot, most of which is caused by abnormal feet. The front of the sole of the outer part of the foot, the second toe or bunions below the joint, are good places for calluses, some calluses will become hard nucleus, the core will grow inside into corns. Some people will be accustomed to use pumice or rubbing knife to remove calluses, but should first soak water to soften, and then gently grinding, so as not to break the skin to produce wounds bacterial infection. 2, foot deformation: normal feet are symmetrical, while deformed feet (such as bunions, m-shaped toes, bent toes) feel somewhat incongruous. Some of the deformation of the foot is born, some are poor posture, improper use caused by, in addition, stroke, spinal injury, neuropathy patients, toes will form claw-like toe bend up, be extra careful. 3, joint mobility: joint activity is composed of bones, ligaments and muscles together, in daily life, if you feel that between the bones often stuck to, it may be a warning sign of foot problems. 4, the degree of shoe wear: normal heel wear is from the outside, while the front of the sole is evenly worn; if the heel wear is excessively severe and on one side, or the front of the sole of the big toe part is very complete, but the second toe part is very worn, or even new shoes not long after serious deformation, may be caused by abnormal feet. In addition, the normal crease in front of the shoe should be horizontal, if it is excessively oblique should also pay special attention. 5, standing posture and gait: stand barefoot in front of the mirror to examine, observe whether the left and right symmetry or bias to one side; walking if there are inward eight, outward eight and lifting the foot when the slight flare of the habit, may also be signs of foot abnormalities. To fundamentally solve the problem of foot pain, we must find out the real cause of foot pain, and with treatment or correction, choose suitable shoes and insoles in daily life, usually let the feet get sufficient rest, treat your feet well, in order to walk a longer road.
