Why Does My Back Keep ‘Going’ When I Bend or Lift?
You bend down to load the dishwasher, pick up a bag from the floor or put on your shoes and suddenly your back seems to “go”.
Perhaps it has happened before. You recognise the sharp pain or spasm immediately and find yourself thinking, “Here we go again.”
Recurring back pain when bending or lifting can understandably make you wary of certain movements. But an episode of pain does not necessarily mean you have damaged your back, and there is rarely one simple explanation for why it keeps happening. Back pain can be influenced by several physical and other factors, and repeat episodes are relatively common.
So, why might your back keep going when bending or lifting, and what can you do about it?
What Does It Mean When Your Back ‘Goes’?
“Going”, “seizing up”, “locking” and “spasm” are all descriptions we regularly hear people use for sudden back pain.
You might feel a sharp pain as you bend forward, find it difficult to straighten up or notice the muscles around your back tightening. Sometimes the pain settles relatively quickly. At other times, you may feel stiff or uncomfortable for several days or longer.
Although it can feel alarming, the intensity of an episode does not necessarily tell us how much, if any, physical damage has occurred.
In many cases of back pain, it is not possible to identify one precise structural cause. The Chartered Society of Physiotherapy (CSP) explains that back pain can involve a combination of factors and that serious structural damage is uncommon.
That is one reason an individual assessment can be useful when episodes keep returning.
Why Does My Back Keep Going When Bending or Lifting?
If the same problem seems to happen repeatedly, it is tempting to assume there must be one weak joint, muscle or disc responsible. In reality, recurring back pain can be more complicated.
You have had previous episodes
Once you have experienced a particularly painful episode, it is natural to remember the movement associated with it.
If bending over once resulted in severe pain, you may become more cautious about bending the next time. You might brace your body, move differently or avoid the movement altogether.
This response is understandable, but becoming increasingly protective of your back can sometimes contribute to reduced confidence in movement. Current guidance encourages people with uncomplicated back pain to remain active and gradually return to normal activities rather than relying on prolonged rest or avoidance.
Your activity has suddenly changed
Think about what was happening in the days before your back “went”.
Had you spent the weekend gardening after months of doing very little? Returned to the gym? Moved house? Carried a toddler more than usual? Spent hours travelling and then lifted a heavy suitcase?
Sometimes the movement that appears to trigger the pain is simply the final part of a bigger picture.
A sudden increase in activity or an unfamiliar load may temporarily exceed what your body is accustomed to. This does not mean bending or lifting is inherently bad for your back. In fact, the CSP advises that people should not fear these movements and that gradually becoming accustomed to different loads can be helpful.
Strength and physical capacity may play a part
If you have become less active, your body may simply be less accustomed to the demands you are placing on it.
Building strength gradually can increase your capacity for everyday tasks, whether that is lifting shopping, carrying children, gardening or exercising. The important word here is gradually. Going from very little activity to suddenly doing much more can be challenging for any part of the body.
There is no single exercise programme that is right for everybody with back pain. The most appropriate approach depends on your symptoms, current abilities and what you want to get back to doing.
Your back may have become more sensitive
Pain is not always a straightforward measure of damage.
Following repeated episodes, some people find that their back becomes more sensitive to movements or loads that they associate with pain. Other factors, including sleep, stress, general activity levels and concerns about further injury, can also influence the experience of back pain.
This does not mean the pain is imaginary. The pain is real. It simply means there can be more contributing to it than one particular muscle, joint or structure.
Should You Avoid Bending and Lifting?
Unless a healthcare professional has advised you otherwise for a specific reason, completely avoiding bending and lifting is unlikely to be the long-term answer.
Your back is designed to move.
After a painful episode, you may need to modify certain activities temporarily and build them back up gradually. Staying active within comfortable limits and progressively returning to your usual activities is generally encouraged for uncomplicated back pain.
You could try:
- breaking larger lifting jobs into smaller amounts
- changing position regularly if you have been sitting for a long time
- keeping up with gentle walking and everyday movement as your symptoms allow
- gradually rebuilding the movements that you have started avoiding
- increasing exercise or lifting loads progressively rather than making a sudden jump
- noticing whether tiredness, unusually busy periods or changes in your routine tend to coincide with flare-ups
There is also no single “perfect” way to bend or lift that guarantees you will never experience back pain. A comfortable technique that suits the task and your current capacity may be more useful than becoming anxious about performing every movement perfectly.
When Recurring Back Pain Is Worth Assessing
One isolated episode that settles may not require professional treatment. But if your back keeps “going”, an assessment can help you understand what may be contributing to the pattern.
At The Octagon Clinic, our chiropractors and physiotherapists can take a detailed history of your symptoms and look at factors such as your movement, strength, mobility, activity levels and the situations in which your pain tends to occur.
Depending on what they find, your care may include advice about managing flare-ups, appropriate exercises and gradual strengthening or hands-on treatment alongside an active rehabilitation plan. NICE guidance recommends that manual therapy, when appropriate for low back pain, should form part of a treatment package that includes exercise rather than being used on its own.
The aim is not simply to focus on the movement that happened immediately before your pain. It is to look at the wider picture and help you find an approach that suits your symptoms, needs and goals.
When Should You Seek Medical Advice?
Most back pain is not caused by anything serious, but some symptoms need prompt medical attention.
Contact NHS 111 or seek an urgent GP appointment if you develop severe back pain that starts suddenly or is getting worse quickly, or if you feel generally unwell, hot, cold or shivery alongside your back pain.
Call 999 or go to A&E if back pain is accompanied by:
- pain, tingling, weakness or numbness in both legs
- loss of feeling around your genitals or anus
- new bladder or bowel changes, such as difficulty passing urine or loss of control.
You should also seek professional advice if your symptoms are persistent or worsening, affecting your usual activities or causing you concern.
Your Back Does Not Have to Feel Like Something You Need to Protect Forever
When your back has “gone” several times, it is easy to lose confidence in everyday movements. You might hesitate before picking something up or wonder whether the next bend will trigger another episode.
But bending and lifting are normal parts of life, and avoiding them indefinitely is rarely the goal.
Understanding your individual pattern, gradually rebuilding strength and movement, and knowing how to respond to a flare-up may help you feel more confident about using your back again.
If recurring episodes of back pain are making you cautious about bending, lifting or everyday activity, our Chiropractic and Physiotherapy teams at The Octagon Clinic can assess what is happening and discuss an approach tailored to you.
