Disease analysis:

Hello: Your problem is chronic muscle strain in the waist and buttocks. The cause of this disease is long-term incorrect posture or bending over to work, or continuous weight bearing on the waist and buttocks, which can cause chronic cumulative injury of local muscles. Your action is to stretch your waist backwards, so the lower back is stressed, so it is muscle injury from the action analysis.

Guiding opinions:

I suggest you go to the hospital to check, diagnose and locate the injured muscle. You can choose acupuncture, massage and small needle knife for treatment.

I wish you a speedy recovery.
