Low Back Pain
What is Acute Low Back Pain?
Acute low back pain is pain felt in the lower back that lasts for a short time (i.e. less than three months)
Most people have pain in their low back at some stage in their lives. In most cases, it will get better in several weeks even without treatment; however, this varies from person to person. Acute low back pain may happen again over time and may progress to chronic low back pain, which lasts for more than 3 months.
What Causes Acute Low Back Pain?
In around 95% of cases it is actually not necessary to know the specific cause and yet the pain can be managed effectively. Most of the time the pain is due to muscles strains. It is rare for the pain to be caused by a serious medical problem. 90% of patients recover from the pain in 6 weeks.
What Should I Do When I Have Acute Low Back Pain?
If your pain bothers you, it is important to see your doctor, to work with them to manage your pain, and to stay active.
Visiting The Pain Physician/Doctor
A history and physical examination are needed to assess for any serious medical conditions that may be associated with your pain, although these are rare.
They can provide you with information about your pain once they have assessed you.
Additional investigations such as x-rays and blood tests, are not needed in the majority of cases of acute low back pain. They do not help with your pain or your ability to move your back.
It is normal to worry about the cause of your pain and the impact it may have on you. Talking to your doctor or specialist about your concerns can be helpful. You will usually find there is no serious cause and that there are ways to relieve your symptoms.
The goal of the consultation is to help you find ways to manage your pain and return to your usual activities.
Most people find that the pain settles down over a short period of time as healing occurs. Pain-relieving measures may help you cope with your symptoms while nature takes its course.
Medications that you can be prescribed include paracetamol, anti-inflammatory medications, and muscle relaxants.
Your pain may make it difficult for you to carry out your usual activities, and you may even want to rest completely.
However, it is important to resume normal activities as soon as possible. Staying active helps to prevent long-term problems.
