Hypermobile Joints & Pain: Why Do Loose Joints Hurt?

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 constantly contract to keep things stable. That ongoing effort leads to fatigue, aching and sometimes sharp pain, particularly after standing, walking or sitting for long periods.

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. An overly flexible lower back can cause tension in the neck. This is why people with hypermobility often feel pain in places that seem unrelated to 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, causing aching, throbbing or restless discomfort that disrupts sleep.

What does hypermobility pain feel like?

Hypermobility pain can show up in many ways. It is often described as a deep ache rather than a sharp, sudden injury. Here are the most common patterns.

Important: If you experience sudden weakness, numbness in both legs, or any loss of bladder or bowel control, please seek urgent medical attention through your GP, 111 or A&E. These symptoms need immediate assessment.

What causes hypermobility pain to get worse?

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

Does hypermobility get worse with age?

Hypermobility itself often reduces slightly with age as connective tissue stiffens. However, the pain associated with hypermobility can increase. By the time you reach your thirties, forties or beyond, years of extra joint movement may have caused cumulative wear, early joint degeneration and patterns of compensation that 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 reveals 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 a lying-down image.

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.

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 typically 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 consultant 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.
