Joints

Overview

A joint is the place where two bones meet. Some joints, like the seams in your skull, hold bones tightly together and barely move. Others, like your knees, hips, shoulders and fingers, are built to move. They let you walk, lift, twist and grip. The ends of the bones are covered with cartilage (a smooth, rubbery cushion), and the joint space holds a slippery fluid that helps everything glide. Strong bands called ligaments hold the bones together, and tendons attach muscle to bone so the joint can move. When any part of this system gets worn, inflamed or injured, you feel it as joint pain, stiffness or swelling.

Yes. Joint problems are one of the most common reasons people visit a doctor, pharmacist or physiotherapist. Nearly everyone has some joint ache at some point, and wear-and-tear joint changes become more common as we get older.

Anyone can be affected, at any age. Joint problems are more likely as you get older, if you have had a joint injury, if you do a physically demanding job or a lot of high-impact sport, if you carry extra weight, or if inflammatory arthritis runs in your family. Children can get joint pain too, though serious causes are rare.

Symptoms

Common symptoms

• Aching or sharp pain in one or more joints, often worse with movement or after resting
• Stiffness, especially first thing in the morning or after sitting for a while
• Swelling or puffiness around the joint
• The joint feeling warm to the touch, or looking red
• Less movement than usual, or trouble with everyday tasks like stairs, opening jars or gripping
• Clicking, cracking or a grating feeling when the joint moves
• Muscle weakness or a feeling that the joint might give way
• Pain that flares up after a busy day or a change in activity

Symptoms in children

• Growing pains are common and harmless: aching in both legs, often in the evening, easing with a cuddle and usually gone by morning.
• Sports injuries, very flexible joints (hypermobility) and occasional inflammatory conditions can also affect children's joints.
• A child with a hot, swollen or very painful joint, a new limp, or who seems unwell should be seen the same day.
• Joint pain with a rash, fever, or that wakes a child at night is a reason to see a doctor promptly.

Symptoms in older adults

• Stiffness after rest that eases with movement is a common pattern in wear-and-tear joint changes.
• Pain in the knees, hips, hands and lower back that builds up over months or years.
• Reduced walking distance, difficulty with stairs, or trouble getting out of a chair.
• Joint pain can increase the risk of falls, so it is worth mentioning to your doctor or physiotherapist.
• Several joints aching at once can sometimes be a sign of inflammation rather than wear and tear, and is worth checking.

Causes

Main causes

• Wear and tear (osteoarthritis): the smooth cartilage cushion gradually thins, which is a normal part of ageing for many people.
• Inflammation: the immune system mistakenly attacks the joints (inflammatory arthritis), or crystals form inside the joint (gout).
• Injury: sprains, strains, torn ligaments or a previous broken bone near a joint.
• Overuse: repeated strain from sport, work or hobbies can irritate tendons and small fluid-filled sacs around the joint.
• Infection: germs getting into a joint — uncommon, but serious and needing urgent care.
• Other conditions: some skin, bowel and gland problems can also cause joint pain.

Risk factors

• Getting older
• A previous joint injury or surgery
• Carrying extra weight, which puts more load on hips, knees and feet
• A job or sport that involves lots of lifting, kneeling, twisting or high-impact running
• Family history of inflammatory arthritis or gout
• Smoking (linked to some types of inflammatory arthritis)
• Being female — inflammatory arthritis and osteoarthritis of the hands are more common in women

When to see a doctor

See a doctor urgently if:

• A joint that is hot, red, very swollen, or painful with a fever
• A joint injury where you cannot bear weight, or the joint looks out of shape
• Sudden severe joint pain that stops you using the limb
• A joint that locks or gives way, especially if you fall

Book a routine appointment if:

• Joint pain or stiffness lasting more than two to three weeks
• Morning stiffness that lasts longer than about 30 minutes
• Swelling that keeps coming back, or affects several joints
• Joint pain that disturbs your sleep or stops you doing everyday things
• Joint pain in a child, or a child who has started limping

Diagnosis

A doctor will usually start by asking about your pain: when it began, which joints are affected, what makes it better or worse, and whether you feel stiff in the mornings. They will look at and gently feel the joint, watch you move it, and may check your other joints too. Often this is enough to point to the likely cause. If more information is needed, they may arrange tests or refer you to a physiotherapist or a joint specialist.

Tests that may be done

• Blood tests to look for inflammation or other conditions
• X-rays to show how the joint looks and whether cartilage has thinned
• Ultrasound or an MRI scan for a closer look at soft tissues, tendons and ligaments
• A small sample of joint fluid, taken with a thin needle, to check for crystals or infection
• A urine test, which can help when gout is suspected

What to expect at your appointment

You may need more than one appointment before the picture is clear, and some tests take a week or two for results. It helps to keep a short diary of your symptoms — what you were doing, how long the pain lasted and how it affected you — and to write down any questions beforehand. Ask your healthcare provider to explain anything that is not clear.

Treatment

Most joint problems are managed without surgery. The aim is to reduce pain, keep the joint moving and help you stay active. A combination of self-care, physiotherapy and, where needed, medicines works best. Your doctor or pharmacist can talk you through the options and help you weigh up the benefits and risks.

Self-care at home

• For a new injury or flare-up, rest the joint briefly, use an ice pack wrapped in a cloth for short periods, and raise the limb if you can.
• Keep gently moving — total rest makes joints stiffer, so aim for light activity that does not make pain worse.
• Pace yourself: alternate activity with short breaks rather than doing everything at once.
• A warm bath, shower or heat pack can ease stiffness, especially in the morning.
• Strengthen the muscles around the joint with simple exercises from a physiotherapist.
• Wear supportive, well-cushioned shoes.
• If you carry extra weight, losing even a modest amount can take a lot of load off hips, knees and feet.
• Protect your joints when lifting: bend your knees, keep the load close, and ask for help with heavy items.

Medical treatments

Treatment depends on the cause. For wear-and-tear pain, the focus is on staying active, physiotherapy and simple pain relief that your pharmacist or doctor can advise on. For inflamed joints, doctors may suggest treatments that calm inflammation; for inflammatory arthritis, specialist teams use medicines that settle the immune system and protect the joints over time. Some people benefit from a steroid injection into a painful joint, or from a physiotherapist-designed exercise programme. Always ask your healthcare provider what a treatment is for, how long to try it, and what to expect.

When is surgery considered?

Surgery is only considered when pain and stiffness seriously affect your daily life and other treatments have not helped enough. Options include procedures to repair or tidy up damaged tissue, and joint replacement for badly worn hips or knees. Your specialist team would explain the benefits, risks and recovery time, and the decision is always yours.

Living with this condition

Living with joint pain is about finding a rhythm that works for you: staying as active as you comfortably can, breaking tasks into smaller chunks, and using aids or gadgets where they help. Many people find that their joints are stiffest first thing and ease as they move, so a warm shower and a few gentle stretches before the day starts can pay off.

Lifestyle tips

• Build regular, low-impact activity into your week — walking, swimming, cycling or tai chi suit many people with joint pain.
• Add gentle strength work for the muscles around your painful joints two or three times a week.
• Try to keep a healthy weight; it is one of the most effective things you can do for your knees and hips.
• Sort out your sleep — pain is harder to cope with when you are tired.
• Consider practical aids such as a jar opener, a long-handled shoehorn or a walking stick, which can make daily tasks much easier.
• If a hobby or job is causing strain, ask a physiotherapist or occupational therapist for advice on adapting it rather than giving it up.

Diet and exercise

There is no special joint diet, but eating a varied, balanced diet with plenty of vegetables, pulses, wholegrains and oily fish supports general health and helps with weight. Staying hydrated matters too. When it comes to exercise, start gently and build up slowly — some discomfort for a day after activity is usually fine, but sharp pain or swelling that lasts more than a couple of days means you should ease off and get advice. Strength, flexibility and balance exercises are the three most useful kinds for protecting joints.

Mental health and emotional wellbeing

Ongoing pain is tiring and can affect mood, sleep and confidence. It is very common to feel frustrated, low or anxious about it, and that is not a sign of weakness. Talking to someone — a friend, your GP, a physiotherapist or a counsellor — helps. If you ever feel hopeless or have thoughts of harming yourself, please reach out for crisis support in your country straight away; you deserve help quickly.

Prevention

Not all joint problems can be prevented — some are part of normal ageing or run in families. But you can lower your risk and protect the joints you have by staying active, keeping a healthy weight, warming up before sport, building strength gradually, and avoiding repeated heavy strain on the same joint.

Vaccines

There is no vaccine that prevents joint problems. Keeping up to date with routine vaccinations is still sensible, especially if you take medicines that affect your immune system — ask your doctor or pharmacist.

Screening programmes

There is no routine screening test for joint problems. If joint disease runs strongly in your family, or you have ongoing symptoms, speak to your doctor about whether any checks are worthwhile for you.

Complications

If left untreated

• Muscles around the joint can weaken, making movement harder
• Stiffness and reduced mobility can build up over time
• Joint pain increases the risk of falls, particularly in older adults
• Ongoing pain can affect sleep, mood, work and social life
• Some types of inflammatory arthritis can damage joints if not treated early, which is why early advice matters

Long-term outlook

The outlook for most joint problems is good. Many people improve with simple measures, physiotherapy and time, and even long-term conditions can usually be managed well so that you keep doing the things that matter to you. Getting advice early, staying as active as you can and asking for support when you need it make the biggest difference.
