Low back pain and sciatica

Most people will have low back pain at some point during their lives. Many people have repeated episodes. This leaflet will explain the following.

• What low back pain and sciatica are.

• What causes back pain.

• What will happen if you do not exercise your back.

• What you can do to help / manage your pain.

• What Cauda Equina Syndrome is, and what the warning signs are.

We hope this leaflet answers some of the questions you may have. If you have any further questions or concerns, please speak to a member of your healthcare team.

What is low back pain and sciatica?

Low back pain is pain located between your waist and buttocks. Sciatica is pain in your leg, caused by a nerve being compressed or irritated in your back.

What causes back pain?

Most back pain is not due to anything serious.

There are several factors which can cause back pain. Often back pain is due to a combination of these factors.

• Physical factors that can cause back pain include stiff joints, tight ligaments, or weak muscles. Unfortunately, the longer these problems exist the more ‘out of condition’ your back will become.

  Your back is designed for movement. It needs movement to improve these problems, remember ‘motion is lotion’. It may cause your back to ache if you:

  • slowly increase your activity levels; and

  • return to normal.

  However, this pain does not lead to harm or damage.

• Your general health and lifestyle can also cause back pain. For example, smoking, being overweight, not being physically active, and not sleeping well.

• Psychological factors which can cause back pain include stress and anxiety.

• Social factors can include stressful life events and difficulties at work and home.

It is a good idea to think about all of the above factors when developing a self-management plan for your back pain. Do not just think about the physical ones.

What will happen if I do not exercise my back?

Being less physically active or changing your behaviour towards movement can lead to you feeling more pain. This can lead to stress and anxiety, which will lead to increased pain and your activity levels reducing further. Remember, if you don’t use it, you will lose it. To avoid this happening, try to stay active.

You can expect to have good and bad periods with your back pain; this is normal. 

When will my back get better?

Improvements in pain vary greatly from person to person. Some people’s pain will get better in a few days, others in a few weeks or months. Sadly, some people have pain for much longer, and can become less active due to having long-term or recurrent pain.

What should I do?

• Painkillers can be helpful for some people with back pain and / or sciatica. Your doctor may prescribe different painkillers, depending on your general health and the type of pain you have. Painkillers may have side effects and some can become addictive. Your GP or pharmacist can discuss suitable painkillers with you.

• If you suffer a flare-up of your back pain, it is common to struggle with certain movements due to the pain. The exercises advised by your physiotherapist will help you to start moving your back again. They will enable you to get back to normal everyday activities, such as putting on your shoes.

• Keep active. We are not designed to be sedentary (sit still). Some people with back pain will find walking or swimming helpful. Others might find they are more comfortable exercising on a bike or in the gym. You can work with your physiotherapist to find the best type of exercise for you and your back.

  If you find it hard to start exercising, try making an action plan with help from your physiotherapist. It is important to build up gradually with any new exercise programme. Government guidelines advise that adults:

  • are physically active for 150 minutes per week; and

  • they do exercises to build strength at least 2 days a week.

  These levels of physical activity will help your back and general health.

• Keep positive. Learning to relax is very important when it comes to managing your pain. Stress and anxiety can put healing on hold.

• Do not avoid normal day to day activities. Doing this will gradually lead to your back becoming stiffer and weaker. If you are struggling with certain activities, you might be able to make some simple changes. For example, when you go shopping you could scan as you shop.

• Pacing allows you to change the way you manage your day. It allows you to slowly increase what you are able to do with less chance of setbacks. Pace yourself when you start to increase your activity levels. Remember that new activities may cause pain but will not cause harm or damage. Speak to your physiotherapist about:

  • developing a pacing diary

  • how to use pacing to manage your back pain

• Setting goals will help your physiotherapist tailor your rehabilitation to your life. Some of your goals will be short-term, and others could be goals you would like to achieve in the long- term. Think about what you would like to do that you are not able to do at the moment. Then problem solve with your physiotherapist on how you will work towards these goals.

How do I deal with flare-ups or setbacks?

Good and bad spells are normal with back pain. The most important thing is to find your own way of dealing with the bad days, so they do not linger for too long. Doctors and physiotherapists can guide you; but here are some useful suggestions.

• Use something to control your pain. Ask your GP or local pharmacist for advice about medication. Some people find heat or cold helpful. If you use a hot water bottle or wheat bag, make sure it is not too hot. If you use ice, protect your skin with a tea towel.

• If necessary, make small changes to your activities for a short time. This might include asking friends and family for help and support, and delegating activities.

• Try to stay active; remember ‘motion is lotion’. This might include taking a short walk or trying some relaxation exercises or gentle stretches.

If you are worried and need further advice, please speak to your physiotherapist or GP.

Do I need tests?

Most patients do not need any tests. Your doctor will normally be able to diagnose simple low back pain or sciatica:

• from your description of your pain; and

• by examining you.

Tests (such as x-rays or scans) are only recommended if:

• we suspect a serious cause for your pain; or

• the test results might change your treatment plan.

How can I manage my back pain and / or sciatica?

There is no quick fix; here is a brief outline of what treatments are available.

• Conservative (non-surgical) treatment

  Most people do not need surgery. Conservative management involves advice and exercises given to you by your physiotherapist.

  Physiotherapy usually includes an assessment of your back, followed by:

  • advice

  • encouragement to gradually return to normal activities

  • home exercises

  It may also involve ‘hands on’ treatment. Your physiotherapist may offer you hydrotherapy, acupuncture, or class-based exercises. What they offer will depend on the results of your assessment and what you would prefer.

  The aim of physiotherapy is to:

  • help you return to your normal activities

  • teach you how to manage your back pain in the future

  Back pain and / or sciatica can reoccur. It is important to continue with your exercises and any lifestyle changes once you have finished your physiotherapy.

• Epidural and nerve root block injections aim to reduce inflammation around your nerves. They can be useful for some patients with sciatica, to help reduce leg pain. Epidurals and nerve root blocks may help you become more active. For more information, please go to the British Association of Spine Surgeons (BASS) web site.

• Surgery

  You and your consultant may decide that an operation is necessary to help you. This could depend on your symptoms and specific test results, such as from x-rays or MRI scans.

  The most common procedure is a discectomy, which reduces sciatica leg pain. After surgery your physiotherapist will give you exercises to help with your rehabilitation. In most cases, surgery is not advised for back pain, only leg pain.

What is Cauda Equina Syndrome?

Many patients have a combination of back pain, leg pain, leg numbness, and weakness. These symptoms can be distressing, but may not need emergency medical attention.

Cauda Equina Syndrome is a rare but serious back condition. It can lead to permanent damage or disability. You will need to be seen by an Emergency Specialist Spinal team. 

What are the warning signs of Cauda Equina Syndrome?

These are some of the warning signs of Cauda Equina Syndrome.

• Loss of feeling / pins and needles between your inner thighs or genitals.

• Numbness in or around your back passage or buttocks.

• It feels different when using toilet paper to wipe yourself.

• Increasing difficulty when you try to urinate (pee).

• Increasing difficulty when you try to stop or control your flow of urine.

• Loss of feeling when you pass urine.

• Leaking of urine or a recent need to use incontinence pads.

• Not knowing when your bladder is full or empty.

• Inability to stop a bowel movement or leaking.

• Loss of feeling when you have a bowel motion (have a poo).

• Change in ability to achieve an erection or ejaculate.

• Loss of feeling in your genitals during sex. 

If you have two or more of these warning signs, go to your nearest Emergency Department or call 111 for advice immediately.

What else can I do to self-manage my back pain?

• Be a healthy weight. Too much weight can put more load and strain on your lower back. The NHS web site has a healthy weight calculator to help you find out whether you need to lose weight, and a 12 week weight loss program.

• Reduce stress, tension, and anxiety, as these conditions can all cause and worsen back pain.
  Web: www.nhs.uk/mental-health/

• Stay active. Regular exercise (such as walking, going to the gym, and swimming) can be helpful, along with regular breaks from sitting.

• Give up smoking. Smokers are three times more likely to develop persistent back pain. One of the reasons is that smoking reduces blood flow to the spine, making it more vulnerable to injury. For free friendly support and medication to help you stop smoking, contact One You Kent.
