First, to sit straight to sit right, so as not to back pain? Sitting posture is to be correct, but not completely straight, after all, the spine has a curvature, the most correct sitting posture is to be able to conform to the shape of the spine. When sitting, the back should have full support, if you sit straight, sit right, but the back is not leaning, because of the lack of support, the back under a lot of pressure. In addition, do not sit too short chairs, and do not sit too deep or too soft sofa, if the chair is not appropriate, even if you want to sit straight is very difficult. Second, when the back pain attack, to rest on the bed until no pain? When back pain strikes, bed rest is a necessary action, and it is true that after bed rest, back pain can be relieved naturally. Different studies have different recommendations on the duration of bed rest, ranging from two days to two weeks. However, bed rest does not mean lying down until you are completely pain-free. This period of bed rest also needs to be accompanied by simple movements that can be done early on. It is recommended to rest completely for the first two days of the back pain attack, and start to do some simple movements on the third day, with the principle of not causing severe pain. 3. Is back pain caused by trauma? It is possible that the back pain is caused by trauma, but there are many causes of back pain, most of which are not caused by trauma, and because lower back pain is so common, it is clinically difficult to link a previous fall with lower back pain. Fourth, exercise will make back pain worse? Depending on the type of exercise, some moderate exercise is needed to prevent or relieve back pain. Running and jumping sports such as basketball, especially jumping movements will increase the vibration of the back spine, which is definitely not suitable for people with back pain. As for swimming, it depends on the patient’s back pain. Usually, after two weeks to a month of back pain relief, swimming can be resumed slowly, and swimming in frog or freestyle will vary depending on the pain. Generally speaking, it is not suitable to exercise when you are suffering from back pain, so it is better to rest more. Some patients think that back pain is due to insufficient exercise, so they walk fast or grab the bar when they have back pain, but as a result, they overexert themselves and make the back pain worse. Patients with back pain should take adequate rest and wait until their symptoms are relieved before seeking professional assistance. The rehabilitator will give exercise advice depending on individual circumstances, especially exercises similar to Pilates to strengthen the back and abdominal muscles to reduce the recurrence of back pain. Five, fat people are more prone to back pain, but thin people do not have back pain? Obese people because of their weight, and lifting heavy objects, the spine is under greater force, relatively easy to back pain, but too thin people, because of the lack of muscle strength, if you need to sit and stand for a long time, the support of the backbone is not enough. Fat and thin on the impact of back pain does not have an absolute relationship, it is best to reduce weight, and increase muscle strength and flexibility. 6. Is back pain caused by lifting heavy objects often? Lifting heavy objects is a gravitational force on the spine, and lifting heavy objects for a long time is an injury to the spine, so it is indeed easy to have back pain, but there are many reasons for back pain. 7. Are people with back pain more prone to osteoporosis? People with back pain may not be prone to osteoporosis, but people with osteoporosis do have an increased chance of back pain. Do young people also have herniated discs? Herniated discs can be seen in both young and old people, but they are more common in young people. Young people, because of the high water content and elasticity of the intervertebral discs, are prone to protrude outward once they are subjected to external forces, while older people have atrophied intervertebral discs, which have become dry and smaller, and are less likely to have protrusions. Nine, people with back pain to sleep in a hard bed? Too soft or too hard bed is not suitable, the most appropriate soft and hard. Commercially available mattresses are always available, as far as the degree of hardness and softness, it is best to have a wooden bed with a 5 cm cushion is the most ideal, the hospital bed is usually such a softness and hardness. Too soft bed will sink when lying on it, but the back is a kind of pressure. As for the hard bed is not suitable, because the human body is irregular surface, sleep hard bed will make the local force is too large. Ten, when the attack should be hot or ice? The same as the treatment of general sports injuries, acute attacks should be iced, preferably within 48 hours, the longest should not exceed 72 hours. Usually young people will be due to sudden slippage of the disc or muscle sprain, such acute attacks should be immediately iced, but if the chronic long-term pain is appropriate to apply heat. 11. Can the disc be retracted by doing rehabilitation? This question has not been conclusively answered. Proper traction can relieve the symptoms, but if the traction is too strong, the herniated part may fall out more, so that it is comfortable at the moment of traction, but after treatment, it is too painful to stand up. However, exercise does increase the strength of the spine, giving the slipped disc a chance to push back to its normal position
