A lumbosacral strain or sprain is one of the most common causes of sudden low back pain — the familiar “I bent over and my back went” experience. It refers to an injury of the muscles, tendons or ligaments at the base of the spine, where the lower back meets the pelvis. Although it can be acutely painful and alarming, it is usually not serious and tends to settle well with sensible care. At Back in Action in Penwortham, we care for people across Preston and Lancashire with this kind of back injury.
Understanding lumbosacral strain and sprain
The lumbosacral region is where the lumbar spine joins the sacrum at the base of the back. It is supported by layers of muscle and strong ligaments that allow movement while keeping the area stable. A strain refers to an overstretch or minor tear of muscle or tendon, while a sprain refers to an injury of a ligament; in practice the two often occur together, and the everyday result is much the same: a sore, stiff, guarded lower back.
This is a soft-tissue injury, which means it follows the general pattern of healing that other such injuries do. The body is well equipped to repair these tissues, and most people recover steadily over a few weeks, particularly with the right approach.
The intensity of the pain can be out of all proportion to the seriousness of the injury, which catches many people off guard. A protective muscle spasm, in particular, can be genuinely severe and frightening, leaving you stuck or unable to straighten up — yet it is the body’s way of guarding the area while it settles, not a sign of serious damage. Understanding this can take a good deal of the fear out of the experience.
What it can feel like
Symptoms typically come on soon after the triggering movement and may include:
- A sudden onset of pain in the lower back, sometimes described as “going” or “giving way”
- Stiffness and difficulty straightening up or moving freely
- Muscle spasm, where the back muscles tighten protectively
- Pain that is worse with movement and eased by certain positions
- Tenderness across the lower back, usually without symptoms travelling down the leg
Unlike nerve-related problems, a simple strain or sprain does not usually cause pain, numbness or pins and needles down the leg; if those are present, we assess for other causes such as a disc problem. The reassuring flip side is that, for a straightforward strain confined to the back itself, the outlook is generally very good.
Common causes and risk factors
A lumbosacral strain or sprain is usually triggered by a specific movement or load, often against a background of factors that made it more likely:
- Lifting something awkwardly, especially with bending and twisting combined
- A sudden, unaccustomed effort or movement
- Reduced fitness or weak supporting muscles
- Fatigue, or repeating a demanding task
- A previous episode, which can make the area more vulnerable
Understanding what brought it on helps us advise you on recovery and on reducing the chance of it happening again. In many cases the underlying theme is that the back was asked to do something it was not quite prepared for, which points towards building a little more strength and resilience as part of getting better.
When to seek help
Most strains and sprains settle within a few weeks, but seeing someone can ease your symptoms and speed your confidence to move. Please seek urgent medical attention if your back pain comes with difficulty controlling your bladder or bowels, numbness around the back passage or inner thighs, severe or progressive weakness in the legs, pain following a significant accident, or feeling generally unwell with a fever.
How long does it take to recover?
Most lumbosacral strains and sprains settle substantially within a few weeks, with the sharpest pain often easing within the first few days as the initial spasm calms down. Some take a little longer, particularly if the area has been injured before or if you return to heavy activity too quickly. The key is a steady, graded return to normal movement rather than either resting completely or pushing straight back into what caused the problem. With that balance, the outlook for a simple strain is very good.
How chiropractic care can help
Chiropractors care for many people with acute and recurrent back strains. In the early, painful stage our hands-on, drug-free care is gentle and focused on easing symptoms and restoring movement, and may include soft-tissue work, gentle mobilisation, and advice on staying as active as comfort allows. As things settle, the emphasis shifts towards rehabilitation to rebuild strength and reduce the risk of recurrence. Because we are a multi-practitioner clinic, we can also draw on physiotherapy and massage. We will be honest about what care can offer and refer you on where appropriate.
What to expect at Back in Action
Your first visit is mostly about understanding your injury. We will take a careful history of how it happened and how it is behaving, and carry out a physical examination of your movement and the affected area, checking that there are no signs pointing to a more involved problem. We will explain what we have found in plain language and agree a sensible plan. You can read more on our new patients page, with current charges on the fees page.
Because a simple strain tends to recover well, our aim is to help it settle as comfortably and quickly as possible, and then to address why it happened so you are less likely to find yourself in the same position again. We will be realistic about the likely timescale and review your progress as we go.
Helping yourself: self-care and recovery
There is a lot you can do to support your own recovery from a back strain, and the modern approach is reassuringly active rather than protective:
- Keep gently moving rather than resting in bed, which tends to slow recovery
- Return to normal activities gradually as comfort allows
- Use simple measures such as heat to ease muscular tension and spasm
- Take care with lifting as you recover, keeping loads close and avoiding twisting
- Build strength and fitness over time to reduce the chance of a repeat
If you would like guidance tailored to you, we can build self-care and exercise advice into your care plan, so that the progress made in the clinic is supported by what you do at home and so that you are better protected against a repeat in future.
Related conditions and treatments
A lumbosacral strain or sprain is closely linked to low back pain and back pain, and where symptoms travel into the leg it can overlap with sciatica or disc problems. The care we provide draws on approaches such as chiropractic manipulation and exercise and rehabilitation, and may form part of a wider plan alongside our chiropractic, physiotherapy and massage services.
