I am a photographer. After taking the photo, my waist hurts particularly. How to treat it? What medicine would be better?

It's best not to take medicine. In fact, low back pain is not a disease, but people's daily bad habits, which can be treated by some relatively simple methods. For example, when you sleep at night, put a canned Coca-Cola bottle wrapped in a dry towel on the bed (unopened, there must be drinks in it). Be sure to lie flat and put the beverage bottle in the position of low back pain, so that your low back pain will be reduced by about 80% in a week, and the effect is obvious!
