The best way is to go to the physical therapy department of a regular hospital and do acupuncture, cupping, massage and other physical therapy, which has a good effect. You can also directly use some drugs for promoting blood circulation and removing blood stasis, such as safflower oil and Litong. Use hot compress, and if the effect is good, you can take oral painkillers, such as fenbid and diclofenac sodium capsules.

The fundamental way is to pay attention to the exercise of back muscles, sleep on a hard bed and keep the waist warm.

The best way to protect the lumbar spine is to exercise the back muscles. This paper introduces two movements, one of which is called "Little Swallow": for example, in the bed at home, take a prone position, take the abdomen as the fulcrum, clamp your arms and stretch backwards as far as possible, put your legs together, stretch your toes as far as possible, and raise your head and neck as high as possible, so as to achieve self-traction of cervical vertebra, thoracic vertebra and sacrum in the best state and achieve tacit movement with surrounding muscle tissues. Secondly, the action of the arch bridge is as follows: supine position, with hands akimbo as the support point, legs bent 90 degrees, feet placed on the bed, upper body supported by occipital part and elbow, lower body supported by two feet, forming a semi-arch bridge shape, and trunk upright. When erecting the trunk bridge, separate your knees slightly to both sides, and repeat 10 ~ 20 times.

I hope it helps you.
