It is important to know and understand whether your back pain is chronic or acute. Chronic back pain lasts for more than three months and is a continuous back pain usually from the result of an injury or illness. Acute back pain can also come from an injury and for other reasons and usually comes on fast and lasts for only a short period of time.
In order to prevent back strains, do not lift anything too heavy. Many times, chronic back pain is caused by someone picking up objects that are too heavy which strains their back. You can avoid this pain by only lifting objects that you know your body, and more specifically, your back, can handle.
