Back pain red flags: when to see a doctor today
Most back pain is mechanical: it hurts, it can stop you working, but it is not dangerous. A small number of warning signs, called red flags, mean the pain may have a serious cause and needs a doctor today, sometimes within hours. Here is what to look for and what to do.
What is a red flag in back pain?
A red flag is a sign that the pain may not be coming from the muscles, joints, discs and ligaments of the back, but from a fracture, infection, tumour, a major blood vessel, or pressure on the nerves that control the bladder and legs.
Ordinary back pain changes with position. Red flag pain often does not, and it may come with symptoms that seem unrelated to the back.
Red flags do not guarantee serious pathology. Their presence raises a probability, not a certainty.
That is enough reason to see a doctor first, rather than booking a massage, stretching or waiting for your next appointment.
When to see a doctor straight away
Go to the nearest hospital emergency department, or call 112 if you cannot travel safely, if you have back pain together with any of the following:
- New difficulty passing urine, or loss of bladder or bowel control.
- Numbness or tingling in the saddle area: the groin, inner thighs, genitals or buttocks.
- Weakness in one or both legs that is getting worse over hours or days, or a foot that starts to drag.
- Back pain with fever, chills and feeling generally unwell.
- Back pain after a significant fall, car accident or sports collision, especially if you are older or have osteoporosis.
- Throbbing pain in the back or tummy that seems to pulse with your heartbeat, particularly if you are over 60.
See your doctor promptly, within a day or two, if:
- You have had cancer at any time and now have new or different back pain.
- You are losing weight without trying.
- The pain is severe, constant and not eased by rest or any position, or it wakes you from sleep and feels deep and gnawing.
- You are over 50 and this is your first ever episode of back pain.
- You have taken steroid tablets for a long time or take medicines that weaken the immune system.
Cauda equina syndrome: why hours matter
Below the end of the spinal cord sits a bundle of nerve roots called the cauda equina. They control the bladder, bowel, sexual function and legs. A large disc herniation, or more rarely a tumour, infection or fracture, can press on them.
The early signs can be subtle and easy to blame on the pain you already have: needing to pass urine but being unable to, numbness “down below”, or heavy, weak legs. In his book, Dr Zano describes a patient who mentioned two of these almost in passing at a chiropractic visit. Treatment was stopped and he was sent straight to hospital, where he had emergency surgery the same day.
If you suspect it, do not wait until morning and do not book a chiropractor or physiotherapist. Go to the emergency department and say clearly that you are worried about cauda equina syndrome. If you were sent home and the symptoms are getting worse, go back.
Other serious causes
Fracture
A fall or accident can break a vertebra. With osteoporosis or after long steroid use, a fracture can happen with very little force. An X-ray or scan is needed before any hands-on treatment.
Infection
Rare but serious. The pain is constant and severe, usually with fever, sweats or shivers. It is more likely with diabetes, a weakened immune system or a recent infection elsewhere.
Cancer
Some cancers spread to the spine. Constant pain that is worse at night, with tiredness or weight loss, needs investigating, especially if you have had cancer before.
Pain from internal organs
Kidney stones or infection, some gynaecological conditions and the pancreas can cause pain felt in the back. It does not change with movement and usually comes with other symptoms, such as urinary changes, fever or tummy pain.
How a good chiropractor screens for red flags
A proper first visit answers one question before anything else: is this back pain safe to treat with manual care at all?
As Dr Zano describes it in his book, a thorough first consultation includes:
- A detailed history: how the pain started, what eases or worsens it, and how it affects sleep and daily life.
- Your medical background: past illnesses, operations, medicines such as blood thinners or steroids.
- Direct questions about bladder and bowel function, saddle numbness, night pain, fever, weight loss and previous cancer.
- An examination of movement, nerves, reflexes and strength in the legs.
A suspected fracture, infection, tumour or cauda equina syndrome rules out spinal manipulation until a doctor has assessed it. Osteoporosis, blood thinners, previous spinal surgery or pregnancy mean the approach must be gentler and adapted. Chiropractic care is not right for everyone, and saying so is part of doing the job well.
Your first visit at Bodywerks costs €70 and includes treatment when appropriate. If treatment is not suitable or an X-ray is needed first, there is no charge, and you leave with a clear explanation of where to go next.
What you can do to stay safe
- Tell your practitioner everything, even if it seems unrelated: previous cancer, blood thinners, a recent urine infection, weight loss.
- Report anything new between appointments, such as numbness, weakness or bladder changes, the same day.
- Share this list with your family. They often notice changes first.
Frequently asked questions
Can back pain be an emergency?
Yes, but rarely. Back pain with new bladder or bowel problems, numbness in the groin or inner thighs, or leg weakness that is getting worse needs the emergency department straight away. Most back pain, even when severe, is not dangerous.
Is back pain that wakes me at night a red flag?
Stiffness from lying in one position is common and usually mechanical. Deep, gnawing pain that wakes you whatever your position, especially with weight loss, fever or past cancer, should be checked by a doctor promptly.
Should I see a chiropractor or a doctor first?
If you have any of the warning signs in this article, see a doctor first. If not, a qualified chiropractor is a reasonable first contact and will still screen for these signs.
What happens if the chiropractor finds a red flag?
Treatment is not started. You get a clear explanation and advice on where to go: your GP, a specialist or the emergency department. At Bodywerks there is no charge for that visit.
If none of the warning signs apply and you want your back properly checked, book online at our clinics in Limassol and Nicosia, or message us on WhatsApp. Dr Zano’s book The Back Pain Blueprint is available at both clinics for €20, and the €20 comes off your next consultation.
