Overview

Knee pain is a common problem that can affect anyone. It can come from an injury, overuse, or a condition like arthritis. Self-care means simple steps you can take at home to help ease pain and keep your knee strong.

Yes, knee pain is very common. Many people experience it at some point in their lives.

Knee pain can affect people of all ages. It is especially common in athletes, older adults, and people who are overweight or have a job that involves a lot of kneeling or lifting.

Symptoms

Common symptoms

• Aching pain in or around the knee
• Swelling or stiffness
• Redness or warmth
• Weakness or giving way
• Popping or cracking noises
• Trouble straightening or bending the knee

• Swelling or limping
• Tenderness over the middle of the knee (common in growing children)

Causes

Main causes

• Injury to ligaments, tendons, or cartilage
• Overuse from repeated kneeling, squatting, or running
• Arthritis, including osteoarthritis or rheumatoid arthritis
• Bursitis – swelling of the small fluid-filled sacs around the knee
• Weight placed on the knee from extra body weight

Risk factors

• Being older
• Playing sports that involve jumping or running
• A previous knee injury
• Having a job or hobby that requires bending the knees a lot
• Muscle weakness or imbalance

When to see a doctor

See a doctor urgently if:

• If you have severe knee pain, cannot bear weight on the leg, or have sudden swelling after an injury, see a doctor the same day.
• If the knee is very swollen or you can't straighten it, seek same-day care.

Book a routine appointment if:

• See a doctor if knee pain lasts more than a few days.
• See a doctor if the pain prevents your daily activities or keeps coming back.

Diagnosis

A doctor will ask about your symptoms and recent activities. They will examine your knee to see how it moves and if there is any swelling or tenderness.

Tests that may be done

• Physical examination
• X-ray to look at bones and joint space
• MRI scan to see soft tissues like ligaments and cartilage
• Sometimes blood tests to check for arthritis or infection

What to expect at your appointment

The doctor will talk with you about what is likely causing the pain and what you can do at home. They may suggest exercises or refer you for physical therapy.

Treatment

Treatment for knee pain depends on the cause and how bad it is. In many cases, home self-care, gentle movement, and simple steps to protect the knee can make a big difference.

Self-care at home

• Rest the knee for a day or two, but avoid staying completely still for long.
• Apply a cold pack for 15 to 20 minutes, several times a day, to reduce swelling. Wrap it in a towel to protect your skin.
• Raise your leg on a pillow when sitting or lying down.
• Use a bandage or knee support for comfort, but not too tight.
• Do gentle stretching and strengthening exercises, as tolerated.
• Use a cane or crutch if it helps take weight off the knee.
• Avoid activities that clearly make the pain worse.

Medical treatments

Medical treatment may include physical therapy to improve strength and flexibility. A doctor or physiotherapist may recommend a walking aid, a knee brace, or in some cases, injections to reduce inflammation. Over-the-counter pain relievers can help, but always ask a pharmacist or doctor before taking any medicine, especially if you have other health conditions.

When is surgery considered?

Surgery is usually only considered when other treatments have not helped and the knee pain severely affects your quality of life. The specific type of surgery will depend on the cause, and your doctor will explain the options.

Living with this condition

Try to keep moving in a way that does not increase pain. Gentle exercise, like walking or swimming, can help keep your joints flexible and muscles strong. Use warmth or cold packs, and take breaks when you need them.

Lifestyle tips

• Maintain a healthy weight to reduce pressure on your knees
• Wear supportive shoes that fit well
• Use proper technique when exercising or lifting
• Give your knees time to rest after heavy activity

Diet and exercise

Eating a balanced diet with plenty of fruit, vegetables, and calcium-rich foods keeps bones and joints healthy. Low-impact exercise, such as cycling, swimming, or using an exercise bike, can strengthen the muscles around the knee without too much strain.

Mental health and emotional wellbeing

Living with knee pain can sometimes feel frustrating or worrying. It can affect sleep and mood. If you feel low or anxious, talk to your doctor. You can also call a mental health helpline in your country for support.

Prevention

You can lower the risk of knee pain by keeping your leg muscles strong, staying at a healthy weight, and avoiding sudden changes in exercise intensity.

Vaccines

There is no vaccine to prevent knee pain, but staying up to date on recommended vaccinations helps keep your joints healthy by avoiding infections.

Screening programmes

There is no routine screening test for knee pain. However, if you have a family history of arthritis, tell your doctor, as they may check for early signs.

Complications

If left untreated

• Ongoing pain and stiffness
• Weakened muscles around the knee
• Difficulty walking or doing daily activities
• The knee giving way, increasing the risk of falls

Long-term outlook

In most people, knee pain gets better with time, rest, and gentle movement. Even when the cause is a long-term condition like arthritis, many people manage their symptoms well and stay active. With the right support, you can live well with knee pain.
