A stiff lower back can make bending and straightening feel restricted, particularly when you first get out of bed or stand after sitting.
Gentle movement often helps, although recurring tightness, worsening pain or symptoms in your legs need a closer look.
A stiff feeling doesn’t identify the cause of your symptoms, so an assessment considers when the discomfort started and how it changes with movement before deciding whether stretching is likely to help.
Causes of lower back pain and stiffness – By Glasgow’s expert physiotherapists
A muscle strain is a common cause of back pain, sometimes following lifting or an unfamiliar increase in activity. These sore back muscles may make you move more cautiously while the area settles.
Back symptoms can also develop without a clear injury.
Time spent in one position, changes in activity, poor sleep and stress may influence how uncomfortable movement feels.
But the causes of back pain aren’t always traceable to a single structure.
When an examination finds no specific underlying condition, clinicians may describe the problem as non-specific low back pain.
You don’t need to identify one awkward bend or blame your posture to start getting help, that’s what the role of a physiotherapist is here for.
Tight muscles and movement in your spine
Your lumbar spine is the lower section of your back, above the pelvis.
Its vertebrae, discs and joints work alongside muscles and ligaments to support movement.
A tight feeling across this area doesn’t necessarily mean a joint is stuck or something needs putting back into place.
We consider hip movement and hamstring flexibility during an assessment. This means looking at how your hip and back move together and whether a particular movement reproduces the discomfort you’ve described.
Other causes of back pain and morning tightness
Some stiffness after a night in bed eases as you get moving.
But persistent morning symptoms deserve more attention, particularly if they last at least 30 minutes, wake you during the night or improve with activity but return after rest.
Morning discomfort alone doesn’t establish the diagnosis, so arrange a medical assessment if the pattern keeps recurring.
Arrange an assessment for persistent symptoms
Book a medical assessment if you have unexplained weight loss, persistent night pain, a change in your back’s shape or a history of cancer with new back symptoms.
New weakness or numbness in one leg also needs prompt advice.
For pain in your lower back that isn’t improving after a few weeks, or is limiting daily activities, an assessment can help establish the next step.
Our back pain physiotherapy always starts with thoroughly checking your symptoms and whether physiotherapy is appropriate.
Gentle ways to ease back pain at home
If your back pain is acute and a short-term flare-up, there are plenty of ways you can help ease it.
Comfortable movements
Keep moving within what you can manage comfortably, provided you have none of the warning symptoms above.
Short walks and changes of position give you a way to stay active without committing to a full workout.
You may need to reduce heavy lifting or shorten an activity temporarily, while continuing manageable parts of your usual day.
Notice how your back responds later as well as during activity.
If a walk leaves you substantially more uncomfortable afterwards, reduce the distance next time.
Build back up gradually as your tolerance improves, and seek advice if the problem keeps worsening.

Heat and short-term comfort
A wrapped heat pack may help relieve pain from muscle spasm and make a stiff back feel more comfortable.
Keep a fabric layer between the pack and your skin, follow the product instructions and remove it if your skin becomes sore.
Ask a healthcare professional before using heat or ice if you have reduced skin sensation or circulation problems, and avoid sleeping with a heat pack in place.
A pharmacist can advise which medicines for back pain relief are suitable for your medical history and any medication you already take.
Sitting and sleeping with a stiff back
Change position regularly if sitting makes your back uncomfortable.
A chair that lets your feet rest on the floor may feel easier to use, but you don’t need to hold yourself rigidly upright throughout the day.
Try a pillow between your knees when lying on your side, or under your knees when lying on your back, if either position feels more comfortable.
Choose the position that lets you rest.
Persistent pain that repeatedly interrupts sleep needs an assessment rather than repeated mattress changes.
Back exercises for lower back tightness
Gentle movement can help relieve a tight lower back, but a stronger stretch isn’t automatically more useful.
Before starting a new exercise routine, seek advice if you’re unsure whether it’s suitable, particularly after a back injury or an operation.
Stop if an exercise worsens your pain, causes pain to travel down your leg, or brings on tingling or numbness.
Seek professional advice before repeating it, and follow the emergency guidance above if warning symptoms develop.
Pelvic tilts
Lie on your back with your knees bent and your feet resting on the floor.
Breathe normally as you gently tip your pelvis to bring the small of your back closer to the surface beneath you.
You don’t need to forcefully flatten your back.
Ease towards your starting position, then gently arch your back a little if that direction feels comfortable.
Pause between movements and keep the range small enough to control without holding your breath.
A gentle knee-to-chest movement
From the same lying position, support behind one thigh as you bring that knee towards your chest, moving only as far as feels comfortable before lowering the foot and trying the other side.
If reaching your leg makes your back hurt, leave this movement out and ask a physiotherapist about an option you can do without aggravating your symptoms.
Build activity as your back settles
Walking or swimming may offer a manageable way to return to physical activity as movement becomes easier, with the amount adjusted to your symptoms and fitness.
Exercises to strengthen the muscles that support your trunk and hips may become part of your recovery.
Core muscles matter for movement, but lower back tightness doesn’t prove they’re weak.
An assessment helps us choose a suitable starting level and decide when you’re ready for more resistance.
Track what you can do as well as how you feel
A useful sign of progress is being able to do more of an activity without a lasting increase in symptoms.
You might notice that dressing becomes easier or that you can walk further comfortably. Improvement doesn’t require every movement to feel completely normal straight away.
Keep a brief note of activities that repeatedly aggravate your back, how long the discomfort lasts and whether the following morning feels different.
Those details help us adjust an exercise programme more accurately than a pain score alone.
Recovery varies with the cause and duration of your symptoms.
Many new episodes improve over a few weeks, while longer-standing problems can take more time and need changes to the exercise programme as you progress.

Our chartered physiotherapists hold HCPC registration, and we explain the findings of your assessment in plain language.
We examine your movement and strength before agreeing a treatment plan.
Your physiotherapy appointments can include advice on activity, exercises to practise between visits and a review of how your symptoms respond.
Hands-on treatment may help with back pain as part of rehabilitation.
Where sports massage is appropriate, we consider it alongside exercise and self-management.
FAQs on stiff lower backs
Does stiffness mean I need a scan?
A scan isn’t routinely needed for uncomplicated back symptoms. Your history and physical examination usually guide the first steps. A clinician may recommend an MRI or other tests if the findings suggest a specific condition and the result would change your care.
Should I stretch my hamstrings?
A hamstring stretch may suit some people, but pulling harder through pain down the leg can irritate symptoms. If you can’t tell whether you’re feeling a muscle stretch or nerve-related pain, ask for medical advice before continuing. The location of the sensation alone won’t reliably distinguish them.
