There must be a reason for the pain, and it is not particularly related to the actual age. If there was an acute lumbar sprain or external injury, or even wind or cold, before this, there will be pain. Standing or sitting for long periods of time and bending over a lot, resulting in strain and strain on the lower back, will of course produce pain. In addition, to be because of urinary tract infections, urinary tract stones can also occur in the case of lumbar pain. And strictly speaking, none of them have an actual age distinction, except that the younger the age, the less likely it is to appear. It is also for this reason that when pain occurs in the waist, you should actively go to the hospital for an examination and have the pain completely resolved, otherwise as you grow older, the pain may get worse or always recur, and at that time it will be more troublesome to treat.
