Pain in the lower back is common. Do you do work that is hard on your body? Then you may suffer more from back pain. For example, if you have to do a lot of lifting, twisting or bending.
Your employer and the company doctor can work with you to see what can be done differently. Then it often manages to keep working and you don't have to call in sick. Usually, the pain at the base of your back will subside on its own.
Sometimes you still have to call in sick. Then your employer and the company doctor will help you get back to work. And to make it less likely that the back pain will return.
