Joint clicking

Overview

Joint clicking, also called crepitus, is when your joints make popping, cracking, or grating sounds when you move. It often happens in the knees, shoulders, fingers, neck, or back. In most cases, it is harmless and not a sign of a problem.

Yes, joint clicking is extremely common. Many people experience it at some point, especially as they age or after periods of inactivity.

Joint clicking can affect anyone, but it is more noticeable in younger people with flexible joints, older adults with wear-and-tear changes, and people who are very active or who perform repetitive movements.

Symptoms

Common symptoms

• Popping or cracking sound when moving a joint
• Feeling of grating or grinding inside the joint
• No pain or swelling – just the sound

Symptoms in children

• Children often have noisy joints due to growing bones and loose ligaments.
• Clicking without pain, swelling, or limping is usually normal.

Symptoms in older adults

• Clicking may be more noticeable due to age-related changes in cartilage and joint surfaces.
• May be accompanied by mild stiffness or ache after rest.

Causes

Main causes

• Gas bubbles forming and bursting in the joint fluid (like cracking knuckles)
• Tendons or ligaments snapping over a bony bump
• Roughened joint surfaces from osteoarthritis
• Joint instability or loose ligaments

Risk factors

• Age – older adults have more wear on cartilage
• Being very flexible (hypermobility)
• Repetitive joint movements in sports or work
• Previous joint injury

When to see a doctor

See a doctor urgently if:

• If joint clicking is accompanied by sudden severe pain, swelling, or inability to move the joint
• If you have signs of infection like redness, warmth, and fever

Book a routine appointment if:

• If clicking is new, persistent, and bothersome
• If clicking is accompanied by mild pain, stiffness, or catching sensation
• If you have a known joint condition like arthritis and the clicking changes

Diagnosis

Your doctor will ask about your symptoms and examine the joint. They will check for pain, swelling, and range of motion. Usually no tests are needed for painless clicking.

Tests that may be done

• X-ray – to look at bone and joint space if there is pain or suspected arthritis
• Ultrasound – to see soft tissues like tendons and ligaments
• MRI – only if the cause is unclear or there is significant pain

What to expect at your appointment

A physical exam is enough for most people. The doctor may move your joint to reproduce the sound. If there is no pain or other concerning signs, they will reassure you that it is normal.

Treatment

Treatment is only needed if the clicking is painful or limits your activities. In most cases, no specific treatment is required. If there is an underlying condition like arthritis, treatment focuses on that.

Self-care at home

• Gentle stretching and strengthening exercises to support the joint
• Applying heat or cold packs if there is mild discomfort
• Taking breaks from repetitive activities that cause the clicking
• Maintaining a healthy weight to reduce stress on joints

Medical treatments

If pain is present, your doctor may recommend physiotherapy to improve joint stability and muscle strength. They may also suggest over‑the‑counter pain relief or anti‑inflammatory medications (ask your pharmacist or doctor). For arthritis‑related pain, treatments such as joint injections or other non‑surgical options may be discussed. Always follow your healthcare provider's advice.

When is surgery considered?

Surgery is rarely needed for joint clicking alone. It may be considered if the clicking is due to a specific mechanical problem (like a torn meniscus or loose cartilage fragment) that causes pain or locking, and if other treatments have not helped.

Living with this condition

Most people live normally with joint clicking. Pay attention to any pain or swelling that may develop. If the clicking bothers you, try gentle movement and avoid staying in one position for too long.

Lifestyle tips

• Stay active with low‑impact activities like walking, swimming, or cycling
• Use good posture to reduce strain on joints
• Warm up before exercise and cool down after

Diet and exercise

A balanced diet rich in calcium and vitamin D supports bone health. Regular exercise strengthens the muscles around joints, which can help reduce clicking. Include both stretching and strengthening exercises.

Mental health and emotional wellbeing

Joint clicking can sometimes cause anxiety or worry, especially if you do not know the cause. It may help to remind yourself that painless clicking is normal. If you feel concerned, talk to your doctor for reassurance.

Prevention

You cannot always prevent joint clicking, but you can reduce the chance of joint problems. Staying active, maintaining a healthy weight, and using proper techniques during exercise and lifting may help.

Complications

If left untreated

• Painless clicking usually has no complications.
• If clicking is due to an underlying condition that is not treated, it may lead to ongoing pain or joint damage over time.

Long-term outlook

The outlook for joint clicking is excellent. For the vast majority of people, it is a harmless noise that does not affect joint health. Even when there is an underlying joint issue, early treatment can manage symptoms and keep you active.
