Hypermobile Joints and Pain: Why Do Loose Joints Hurt?

Hypermobile joints hurt because the ligaments that normally keep them stable are looser than usual. Your muscles have to work much harder to make up for this. Over time, this extra effort causes tiredness, aching and sometimes inflammation. This is most common in the weight-bearing parts of the body, such as the spine, hips and knees.

Key points

  • Loose ligaments force your muscles to steady joints they were not designed to support on their own.
  • Pain often appears away from the loosest joint, because the body compensates in the joints above or below it.
  • Scans done lying down can miss alignment problems that only show up when you are standing and bearing weight.
  • A whole-body standing image maps how every joint lines up under gravity, showing hidden compensations.
  • Knowing your alignment helps your physiotherapist or specialist focus on the right area.

Why do hypermobile joints hurt?

Hypermobile joints hurt because the connective tissue that supports them is stretchier than normal. So it does not hold the joint firmly in place. When ligaments are too loose, your muscles must keep tightening to keep things stable. That constant effort leads to tiredness, aching and sometimes sharp pain, especially after standing, walking or sitting for a long time.

Think of your body as a chain. Your feet, knees, hips, spine and shoulders all depend on each other for balance. If one link in the chain is too flexible, the joints above or below it compensate. A loose hip can lead to knee pain. A lower back that is too flexible can cause tension in the neck. This is why people with hypermobility often feel pain in places that seem to have nothing to do with the loosest joint.

Hypermobility pain at night is also common. During the day, your muscles actively brace the joints. When you relax in bed, those joints may settle into slightly misaligned positions. This can cause aching, throbbing or restless discomfort that disturbs sleep.


What does hypermobility pain feel like?

Hypermobility pain can show up in many ways. People often describe it as a deep ache rather than a sharp, sudden injury. These are the most common patterns.

Deep, widespread aching A general, tired ache through the back, hips or legs, often worse after activity.
Joint clicking or popping Frequent clicks, pops or a feeling of the joint shifting in and out of place.
Tiredness after standing or walking Muscles tire quickly because they are working overtime to keep joints stable.
Night-time pain or restlessness Aching that gets worse when lying still, making it hard to find a comfortable position.

Important: If you have sudden weakness, numbness in both legs, or any loss of bladder or bowel control, please get urgent medical help from your doctor or the nearest emergency department. These symptoms need to be checked straight away.


What makes hypermobility pain worse?

Several things can make hypermobile joints and pain more troublesome over time. The looseness itself is usually genetic. But the pain often gets worse because of how your body responds to it.

Muscle deconditioning Pain leads to less movement, which weakens the muscles that support your joints.
Compensating posture Your body shifts weight to avoid the painful joint, creating new strain somewhere else.
Repeated small injuries Joints that keep moving beyond their normal range develop low-grade inflammation.
Ageing Ligaments and cartilage lose resilience with age, adding wear to joints that are already loose.

Does hypermobility get worse with age?

Hypermobility itself often reduces slightly with age, as connective tissue stiffens. However, the pain linked to hypermobility can increase. By your thirties, forties or later, years of extra joint movement may have caused build-up of wear, early joint degeneration and patterns of compensation. These pile strain onto areas like the lower back, hips and knees.

This is why many adults with hypermobility say they coped well as teenagers but now struggle with persistent pain. The range of movement may look less dramatic, but the damage beneath the surface has had time to build.


How does a standing scan help with hypermobility pain?

A standing whole-body scan shows how your skeleton actually lines up under gravity. This matters for hypermobility, because the compensations that cause pain only appear when you are upright and bearing weight. When you lie down for a standard X-ray, CT or MRI, gravity is removed, your muscles relax and your joints settle into a different position. Problems that bother you every day can look normal on an image taken lying down.

An EOS scan captures your full skeleton in one image, from your ankles to your skull, while you stand naturally. It uses about 90% less radiation than a standard X-ray, around ten times less. Because it shows every joint in context, your clinician can trace how a loose hip, a tilted pelvis or a curved spine affects the joints above and below it.

When MRI is the better choice: EOS shows bones, joints and alignment. If your clinician suspects soft-tissue problems such as ligament tears, disc injuries or nerve compression, MRI is usually the more suitable test. In many cases, the two types of imaging work well together.


What helps manage hypermobility joint pain?

There is no single fix for hypermobility pain, but understanding what is happening inside your body is a strong starting point. Management usually focuses on building strength around the joints, so that muscles can do the stabilising job that loose ligaments cannot.

Targeted physiotherapy is widely recommended. The best exercise for hypermobility pain tends to be low-impact, controlled strength work. Swimming, Pilates and guided resistance training are often suggested, because they build stability without forcing joints past their safe range.

Accurate imaging plays an important role here. If your physiotherapist or specialist can see exactly where your alignment is off, they can design a programme that targets the right muscles. Without that full picture, treatment can end up addressing symptoms rather than root causes.

Before you start treatment, or change the one you are on, it is worth getting a detailed diagnosis. Knowing whether the cause sits in your pelvis, your legs or your spine changes what will actually help.

ScanAlign is a diagnostic imaging clinic. We do not provide treatment. We provide the detailed whole-body alignment data that helps your treating clinician make better decisions. You can learn more about how EOS whole-body imaging works on our overview page.


Frequently asked questions about hypermobile joints and pain

During the day your muscles actively brace your joints. When you lie down and relax, loose joints can drift into slightly misaligned positions, causing aching and restlessness. Supportive pillows and gentle positioning can sometimes help.

"Double-jointed" is the everyday term. In medical language, it means your joints have a greater range of movement than average. Not everyone with extra flexibility has pain, but many do, especially as they get older.

Yes. A hypermobile lower back may move too much under load. This causes muscle tiredness, stress on the discs and compensating stiffness in the mid back or hips. A full-body alignment image can show how these areas affect each other. You can read more on our spine alignment page.

Low-impact, controlled strength training is generally recommended. Pilates, swimming and guided resistance work help build the muscle support that loose ligaments cannot give. A physiotherapist experienced in hypermobility can tailor a programme to your needs.

No. ScanAlign accepts self-referrals. You can book directly without needing a letter from your doctor or specialist.

An EOS scan uses about 90% less radiation than a standard X-ray, around ten times less. This makes it one of the lowest-dose skeletal imaging options available.

Hypermobility is diagnosed clinically, usually through a physical examination. What an EOS scan does is show the effects of that hypermobility on your alignment, such as pelvic tilt, spinal curves and differences in leg length, while you stand under real load.

Yes. Loose hip and knee joints can lead to early wear, clicking and pain. Because the legs carry your full body weight, even a small shift in alignment can have a noticeable effect. Learn more on our hip alignment page.

For patients travelling from abroad, the price is confirmed during the free video consultation. You can also see our FAQs and cost page.

When you lie down, gravity is removed and your muscles relax. Joints settle into a different position, and compensating shifts may disappear. A standing scan captures your skeleton as it actually behaves in daily life, showing the misalignments that matter most.
