Patient: Pain in the lower back, which used to hurt after bending over for a long time, but will get better after resting. In the past half a month or so, the pain is constant and does not get better after resting. I have not been treated for lumbar muscle strain, so how should I treat it? What should I pay attention to in my daily life? Does it have anything to do with the bed? Doctor: There are many causes of lumbar pain, and the main points to identify “lumbar muscle strain” are as follows: 1) the onset of lumbar strain; 2) the possible history of lumbar “cold”, such as air conditioning, electric fans, poor lumbar warmth during sleep; 3) poor lumbar rest, such as a long period of time history of lumbar fatigue (long hours of seat work, bending work), lack of sleep; 4, not accompanied by pain or numbness and weakness of the lower limbs; 5, lumbar mobility is not affected; 6, no obvious pressure pain or percussion pain points in the lumbar region; 7, “pounding” behind the waist has a clear sense of comfort; 8, lumbar spine imaging examination is not obvious pathological changes. If there is any discrepancy, please see a specialist at the hospital. The treatment of lumbar strain is mainly self-care, keep warm, ensure sleep, avoid excessive excessive bending or seat activities (when the seat pay attention to the waist straight), regular exercise, keep the weight not too heavy, sleep in a bed not too soft, after paying attention to these, is able to cure.
