4 out of 5 adults have back pain during their lifetime
Low back pain can develop gradually over time or be triggered by an everyday movement at home or at work. It is frequently caused by a combination of factors such as lack of exercise, stress, feeling run down and muscle strain or ligament sprain. Back pain can also be caused by sciatica, spondylosis or stenosis. Less than 1% of back pain is caused by a serious condition and health care professionals screen for these in their assessment.
There are two kinds of low back pain - acute and chronic/persistent.
Acute low back pain is incredibly helpful (though it may not feel like it at the time). It alerts us to a tissue injury to make us protect it from further damage. If you think of the nervous system like a burglar alarm - then pain is the loud noise it makes when it senses a problem. As the injured tissue heals it no longer requires protection and the pain lessens and then stops in less than 3 months.
Chronic or persistent low back pain pain is pain that lasts more than 3 months or reoccurs. Unlike acute pain it is not usually caused by tissue damage or injury. The pain response is caused by the body's nervous system becoming over sensitive - like when the burglar alarm is set off by the family cat or a spider crossing the sensor. The sensors would still trigger the alarm if a burglar came in but they also trigger when anything else moves and are more sensitive than we need them to be. We have nerves all over our body - they send messages about pressure, touch, temperature up the spinal cord to our brain. The brain receives the messages and adds it in with messages it has had before from previous experiences. It adds this in with messages about our current stress levels, our mood and our beliefs about the current situation and in a nanosecond it produces a pain response. The brain, the spinal cord and the brain can all become sensitive to chronic/persistent pain - without there being any harm or damage to your tissues.
HURT DOES NOT = HARM
I
want to make it absolutely clear at this point - you are not imagining the pain - it is not "in your head" - it is very real - but may not be caused by a tissue injury. Researchers have now categorised this pain as completely different to the acute pain you get when you hit your thumb with a hammer. Once you understand pain you can take positive steps towards turning down the pain system's sensitivity levels.

What causes back pain? Myth busting..... Lifting Heavy Weights
Contrary to popular belief lifting heavy weights does not cause back pain. Instead of avoiding lifting heavy items such as shopping bags, toddlers, hay bales you should gradually build up the weight you lift each day to strengthen it. Back pain is often caused by stiffness from inactivity and muscle deconditioning.
If you have not lifted any heavy things for a while then start by keeping the weight close to your body and progress slowly using everyday items such as a bag of shopping or a pile of books. People who go straight to lifting heavy weights may cause an injury and pain. Slowly and gradually is the key to success.
Twisting and Bending
People avoid twisting and bending as they have heard that it causes back pain - this is very outdated advice and the evidence suggests the opposite is true. Our backs have evolved to rotate, twist, extend, flex and bend and by going against the natural movement of the spine. In fact our spine is more stable when it is curved. The outdated advice of "bend at the hips and keep your back straight" does not avoid back pain or injury. The best option is to bend and twist within your own comfort zone.
To help improve your flexibility and strength you may like to try Pilates - I can highly recommend Pilates with Clare Palmer www.pilateswithclarepalmer.yondo.com Clare is a very experienced Pilates instructor and has videos that can be streamed at home.
Exercise
Research has shown us that lying down in bed or on the sofa does not help back pain - in fact it can make it worse as your back muscles decondition and become weak and your stamina levels reduce. When we do not move because of pain or when we try and move in a different way - the brain still receives a signal even when the pain has gone.
By trying to protect your back by moving around in a slow and cautious way is hard work for your spine - it makes the muscles overwork causing more aching and spasms. This adds more load on the joints and discs in your back which increases their sensitivity too.
If you have low back pain then physical activity and exercise is usually the way to resolve it. I don't mean that you need to run or join a gym (unless you want too!). If you have never exercised, if you haven't exercised for ages if you are near to 90 years old - it does not matter- there is some form of physical activity or exercise that you can do that will help. Exercise is good for keeping your joints healthy and improving your fitness levels and health.
When you do some physical activity and exercise your body releases endorphins which is a " feel good" hormone and a natural painkiller. The latest evidence shows that exercise can reduce back pain and that active people recover more quickly. When you are in severe back pain this can be difficult, but just keep trying to move around and increase it by a little each day.
The good side effects of exercise are feeling more in control of the pain, sleeping better, reduction in anxiety and stress, weight loss and an improvement in your feelings of well being. It does not require you join a gym or buy lots of expensive equipment - walking, gardening, cycling, swimming, yoga and pilates are all suitable levels of activity. If you struggle sticking to any regular activity choose one you enjoy and ask a friend to join you. You don't have to go to a class you can do them online too.
Pacing activity
When you feel low back pain during your daily activities such as walking, household chores, gardening or work you may think that this means you are causing damage and stop your activity. This is not a good way of helping yourself as it leads to avoiding activities and creates a less active lifestyle. It is not the activity that causes the pain - the intensity of the activity is the reason for the pain.
When you are having a good day it can be tempting to try and get a lot of things done which suddenly increases your activity level, by overdoing it this increases the pain and requires a longer rest period to recover. When you pace yourself you avoid these pain flare ups. By alternating activity and rest periods so that you have an even amount of activity and rest each day this allows you to continue you activities. By slowly increasing the activity over several weeks your body will adapt to the increased levels without raising the pain alarm.
Pain, mood and anxiety
People with chronic/persistent pain are highly likely to experience low mood, stress, worry and anxiety. Feeling low in mood can make pain feel worse and can lead to a viscious cycle of worsening mood and increasing pain. Hormones including adrenalin are released when you feel stressed and low in mood which also happens when you are injured. This results in your pain sensitivity increasing. Whilst we often dismiss cold sores or headaches as a result of feeling stressed or a bit run down we do not seem to consider a bad back can be triggered in the same way.
When chronic/persistent pain has prevented you from doing all the things you want to do, it is normal to become frustrated, angry, anxious or low in mood. It can also leave you without motivation to become active again which can lead to weight gain, increased pain and inactivity. Focussing on the pain and avoiding activity will only increase the pain level. Therefore it is important to keep being active and find ways to distract yourself from the pain, by doing something you enjoy. Walking whilst chatting to a friend is a good way to start.
Managing a flare up
When you have a sudden increase in pain it is known as a flare up - this can even happen when you have had no pain for a long time and been doing everything well. Overdoing activity or feeling run down often coincide with a flare up. Usually flare ups settle down with a few weeks of doing the right things.
When you are experiencing a flare up reduce your exercise by half, but keep moving about gently and gradually increase you activity daily. Breaking tasks up into manageable chunks with rest periods in between can help.
Follow your pharmacist or GP's advice about pain relief medication and when you need to take it.
Should I have a scan or an x-ray?
MRI scans and x-rays are usually unnecessary in most cases of low back pain. Scans and xrays just show the picture of your lower back at that time - it doesn't show your pain or everything associated with your pain. In fact the results of an MRI scan can mislead us to presume your pain is caused by something which isn't causing the pain. Take a look at the picture below which shows how many people
without
pain had a result from a scan 87% of people aged 20-70 had a disc bulge. A scan may lead to recommendations for more invasive treatments such as injections and surgery which most people do not need to reduce their low back pain. People who have had back surgery often do not experience major improvement in their symptoms after one year.
MRI scans are usually only needed if you have:
A loss of bladder or bowel control
Urinary retention ( unable to empty your bladder completely)
Altered sensation between your legs and/or around your genitals
Progressive loss of sensation and weakness in your legs
