If a patient wakes up with back pain and cannot get up, it may be due to the following reasons: First, it may be caused by excessive fatigue of the lumbar muscles, for example, the patient worked for a long time bending over the previous day, which may cause fatigue of the lumbar muscles. The patient’s symptoms may not be serious at this time, but after a night’s sleep, the patient may have muscle fatigue and a large amount of lactic acid deposited inside the muscle, which then leads to great pain in the lower back, and the patient is not even able to get up. Secondly, it may be caused by sprain and contusion of the lumbar muscles. The patient sprained the lumbar area during the lifting of heavy objects on the first day without special treatment, and after sleeping for one night, the lumbar muscles may be sprained and produce a particularly serious inflammation, which then causes the above symptoms. Thirdly, it is also common that the patient has a deficiency of kidney essence and has the waist affected by cold, damp and other evil spirits. In this case, the patient will have the above symptoms and feel like the waist is broken.
