Acute low back pain refers to pain in the lower back which has lasted for less than 12 weeks. The lower back is the region of the body where the lumbar spine is located. The lumbar spine is the bottom section of the spine and consists of fve bones
(vertebrae). Between these vertebrae are structures called discs which act as shock absorbers. There are countless muscles acting on the lumbar spine and a number of strong ligaments which provide the spine with stability. Many of these structures can be involved when you experience acute low back pain.
Lower back pain can unfortunately happen to anyone at any time. Around 70% of Australian adults will experience lower back pain at some point during their life.
What causes back pain?
Acute low back pain can be caused by many factors such as:
• trauma (fall, car accident, lifting)
• muscle imbalances (postural issues)
• existing medical conditions
• rheumatological conditions.
Injuries can happen when you do something new, different or strenuous, such as lifting heavy items or playing a new sport. The pain may also occur because of a build-up of stress on the back that gradually turns into an injury. Although serious causes of back pain are rare, it is important that you have your condition assessed by a qualifed health professional such as a physiotherapist. This is particularly important if your back pain is associated with other symptoms like fever, unexplained weight loss, pins and needles or numbness, or if your pain was caused by a high velocity trauma such as a car or sporting accident.
What should you do?
At the frst sign of back pain, there are a few simple things you can do to provide short term relief and give your back
the best chance of healing quickly.
• Stay active: It may be tempting to stay in bed, it is important to keep moving as much as you comfortably can. By doing this, you can prevent stiffness and relieve muscle spasms. Your physiotherapist can prescribe a gentle exercise program tailored to suit your condition. They can also gradually progress your exercises to help you return to normal function as soon as possible.
• Use heat: Heat has been shown to improve pain and function during the frst 48 hours of back pain. A few easy options are heat wheat bags and hot water bottles. Make sure you test the heat before you apply it.
• Find comfortable positions: Although you should remain as active as possible during the early stages of back pain, there are times when you need to be lying or sitting down. Find positions that allow you the most comfort, especially when sleeping. Using a pillow under the knees when lying on your back and between your knees when lying on your side can offer support and relief from pain. When sitting ensure your lower back is supported. You can use a rolled up towel placed in the small arch of your back. This will help provide support and may relieve the pain.
• Stay positive: Back pain is a distressing and disabling condition, but it is important to remember that you will get better. With proper treatment you should regain normal, pain-free movement as well as improving the strength of
the key supporting muscles that surround your spine.
