By preventing it will stop you from having a lifetime of back pain.
For some the pain will only be there for a day or two, but for many the back pain will last much longer and maybe even for the rest of their lives. Back Pain can be stopped before it starts to be a problem. Many back pain problems are caused by bad posture. There is a great number of physiotherapists who claim that muscle imbalances are in fact the largest cause of back pain.
Our backs need to be exercised, they need to be stretched. At least one time in everyone's lifetime they will have some sort of back pain. Fortunately posture of many people has greatly increased from the use of computers. Having a back that is not active for a long period of time can get weak and therefore there will be more pressure put onto bone joints which can cause some very painful situations. Keep the stresses that you put on your back before you do anything. Back Pain that is chronic or severe had been treated by relieving the imbalances of the muscles that support the spine and the pelvis.
Besides from sitting proper at your desk you should also consider taking some brakes to walk around to increase circulation.
Prevention matters need to be taken and they will work better then any cure. By bending your knees before you lift it prevents all of the weight from being placed on your back. There is good news though. When you need to lift on anything that is heavy you should always have help and you need to bend your knees.
