Back pain is one of the most common reasons people seek medical advice, and one of the most common worries I hear in clinic is a simple one: will I need an operation? It is a very reasonable question, and the answer, for the great majority of people, is reassuring. Most back pain settles without surgery, and surgery is needed in only a small proportion of cases.
In this article I want to explain, in plain terms, when surgery for back pain is genuinely necessary, when it is not, and what is usually tried first.
It is worth saying clearly at the outset: the majority of lower back pain is mechanical. It comes from the normal wear and tear changes that happen to the spine as we age, or from a temporary strain, and it tends to settle with time and simple measures. Severe pain can be frightening, but pain levels do not always reflect the seriousness of the underlying cause. Very often, intense back pain is the result of something entirely benign that will improve on its own.
For this reason, surgery is rarely the first answer. Jumping to an operation for ordinary back pain risks all the downsides of surgery without a clear problem for it to fix.
Before surgery is ever considered, there is a great deal that can help. Conservative treatment – that is, treatment without an operation – is the right starting point for almost everyone. This usually involves:
Where pain is more persistent, other measures such as targeted injections may have a role. The aim throughout is to recommend the least invasive approach likely to help.
Surgery for back pain alone is uncommon. It becomes a consideration in specific circumstances, usually where there is a clear structural problem that matches the symptoms and has not responded to other treatment. More often, surgery is helpful not for back pain itself but for the leg pain, numbness or weakness that can come with it when a nerve is being compressed – conditions such as sciatica or spinal stenosis.
There are also a small number of situations where surgery is needed more urgently. If back pain is accompanied by difficulty controlling the bladder or bowels, numbness around the back passage or inner thighs, or progressive weakness in the legs, this needs urgent medical attention, as it can occasionally signal a more serious problem.
If surgery is ever suggested to you, it is reasonable to ask: what specifically is the operation aiming to fix, how confident are we that this is the cause of my symptoms, and what happens if I wait? A good spinal surgeon will welcome these questions and answer them honestly. Surgery should only go ahead when there is a clear problem to address and a realistic expectation that the operation will help.
If your back pain is severe, is not improving after several weeks, or is associated with pain or weakness travelling down the leg, it is sensible to seek a specialist opinion. As a Consultant Neurosurgeon in Cambridge, I am able to assess your back pain, explain clearly what is causing it, and guide you towards the most appropriate treatment – which, in most cases, will not involve surgery at all.
