In daily life, many young women like to wear high heels, the height of high heels is generally about 4 to 6 cm, or even higher. After wearing high heels, the height of the heel makes the body’s center of gravity correspondingly higher, in order to stabilize the original balance lost by the body’s center of gravity change, the body’s muscle tension, especially the lumbar back muscle tension will be readjusted to create a new state of balance. People wearing high heels, because of the pelvic tilt enhanced, the line of gravity through the back of the pelvis, so that the waist to support the weight and increased burden, and then after the extension enhanced, long-term sustained, will be due to excessive contraction of the lumbar back muscles and lumbago. For every 1 cm increase in heel height, the posterior extension of the lumbar spine and the contraction of the lumbar back muscles will increase exponentially, and the chance of low back pain will become greater and greater. This shows that it is not appropriate for sciatica patients to wear high heels, and in order to prevent low back pain, it is best for the general public not to wear high heels regularly. So is it better for people with low back pain to wear flat shoes? In fact, flat shoes are not necessarily absolutely beneficial, choose a heel height of about 3 cm is more appropriate. Therefore, patients with low back pain may wish to change a pair of appropriate shoes, may make the back pain will be alleviated. Sciatica occurs in women after pregnancy, the majority of which is caused by lumbar disc herniation, which is obviously related to the special physiology during pregnancy. One is the physiological changes in the endocrine hormones of pregnant women, making the joints and ligaments relaxed and ready for childbirth, which invariably makes the stability of the lumbar region weaken. Second, the fetus gradually develops and grows in the womb, which increases the burden on the lumbar spine, and this burden persists until delivery. On top of this, if there is further strain and sprain between the lumbar vertebrae, a lumbar disc herniation is likely to occur, thus compressing the sciatic nerve, causing edema and congestion and producing sciatica, the sciatic nerve irritation. It is best not to do an x-ray examination for this sciatica in the mother-to-be, but to apply an ultrasound examination instead. Even if it cannot be replaced, the examination should be arranged in the second trimester, when the fetus is close to maturity and less likely to cause adverse reactions. Pregnant women should prefer to rest on a hard bed and do traction treatment; conventional belt girth tends to restrict the fetus’ activities and is not conducive to its development, so it should not be used; because herbs that activate blood circulation and remove blood stasis can affect fetal development, they should be prohibited. Certain drugs, although effective, are also not advocated for use at this time. If the symptoms are severe in the middle stage, termination of pregnancy can be considered. At the time of delivery, a caesarean section is recommended to avoid aggravating the condition. In general, most mothers-to-be can recover from sciatica on their own after delivery, and only a few need surgery after delivery. The key to prevention is to combine work and rest during pregnancy and avoid strenuous physical activities, especially in the 3 months before delivery. It is best to sleep on your side, put a pillow or cushion under your knee when lying down, and don’t wear high heels.
