When to see a doctor
See a doctor urgently if:
- Pain after an injury that causes swelling, deformity, or inability to bear weight
- Signs of infection: fever, hot and red knee
- New pain that is severe and not getting better
Book a routine appointment if:
- Pain that lasts more than a few weeks
- Swelling that does not improve
- Limitations in walking or daily activities
- Wanting a proper diagnosis and treatment plan
Diagnosis
Your doctor will ask about your symptoms, how the pain started, and what makes it better or worse. They will examine your knee, checking for swelling, tenderness, range of motion, and stability.
Tests that may be done
- X-rays
- MRI (magnetic resonance imaging) scan
- CT scan
- Ultrasound
- Joint fluid analysis (taking a small sample of fluid from the knee for testing)
What to expect at your appointment
The doctor may ask you to move your knee, walk, or squat. They might also press on different areas to find where it hurts. Based on what they find, they may order imaging tests or refer you to a specialist.
Treatment
Most knee pain gets better with a combination of rest, ice, gentle movement, and guided exercise. Some conditions need more specific treatment from a healthcare professional.
Self-care at home
- Rest the knee and avoid activities that cause pain
- Apply an ice pack for 15 to 20 minutes several times a day (use a cloth between the ice and skin)
- Gently move the knee with simple stretches and range-of-motion exercises
- Keep the leg elevated when you can
- Use a supportive shoe or a knee sleeve if it helps
Medical treatments
Treatment depends on the cause. Physical therapy is often recommended. Pain relief medicines (such as over-the-counter options) can be used, but talk to your doctor or pharmacist first. Other options may include corticosteroid injections or other injected treatments, which are given by a healthcare professional.
When is surgery considered?
Surgery is only considered when other treatments have not helped and the problem is structural, such as a torn cartilage, ligament damage, or severe arthritis. Your doctor will discuss options and what to expect.
Living with this condition
If you have knee pain, plan your day so you can rest the knee when needed. Use aids like a crutch or a walking stick if advised. Pace yourself, and try to keep up with activities that do not increase pain.
Lifestyle tips
- Maintain a healthy weight to ease pressure on your knees
- Choose low-impact activities like swimming or cycling
- Strengthen your thigh and leg muscles with gentle exercises
- Warm up before exercise and cool down afterward
- Wear shoes with good cushioning and support
Diet and exercise
A balanced diet supports overall health and can help you manage your weight. Regular, gentle exercise keeps your joints moving and strengthens the muscles around your knee. Talk to a physical therapist or qualified exercise professional if you need help.
Mental health and emotional wellbeing
Living with ongoing knee pain can be frustrating and can sometimes affect your mood. It is normal to feel low or anxious. Talk about it with your healthcare team, family, or friends. Remember that treatment and support are available.
Prevention
Not always, but you can reduce your risk. Keeping your leg muscles strong, staying a healthy weight, and avoiding sudden changes in activity levels can help protect your knees.
Complications
If left untreated
- Long-term (chronic) pain
- Worsening arthritis
- Instability or repeated giving way of the knee
- Loss of cartilage or joint damage
- Reduced ability to walk or do daily activities
Long-term outlook
The outlook for knee pain is generally good. Many people improve with simple measures and exercise. Even for people with arthritis, the right treatment can ease symptoms and help you stay active. With a clear plan and support, you can often keep a good quality of life.
