long lasting knee pain

Overview

Long-lasting knee pain is pain in or around the knee that continues for weeks, months, or longer. It can be a dull ache, a sharp stabbing feeling, or a constant soreness that makes everyday activities difficult.

Yes. Long-lasting knee pain is one of the most common reasons people visit a doctor, especially as they get older.

It affects people of all ages, including children, but it is more common in adults over 45, people who have had a knee injury, and those living with obesity.

Symptoms

Common symptoms

• Pain when walking, climbing stairs, or standing up
• Stiffness, especially in the morning or after sitting still
• Swelling or tenderness around the knee
• A feeling that the knee is giving way or locking
• A creaking or grinding feeling when you move the knee

Symptoms in children

• Pain that gets worse with activity or sport
• Swelling or redness around the knee
• Pain that improves with rest but returns when the child is active again

Symptoms in older adults

• Aching pain that increases with activity
• Morning stiffness that eases after a few minutes of movement
• Pain when bending or straightening the knee
• Trouble with walking, stairs, or getting in and out of a chair

Causes

Main causes

• Osteoarthritis – 'wear and tear' of the cartilage that cushions the joint
• A previous injury, such as a ligament or meniscus tear
• Tendonitis – inflammation of the tendons around the knee
• Bursitis – swelling of the fluid-filled sacs near the knee
• Rheumatoid arthritis or other types of inflammatory arthritis

Risk factors

• Getting older
• Being overweight or living with obesity
• A past knee injury
• Repeated stress on the knee from certain jobs, sports, or activities
• Weak thigh or calf muscles

When to see a doctor

See a doctor urgently if:

• If you have a fever along with swelling and redness in the knee
• If you are unable to bear weight through the leg
• If the knee looks unusually twisted or misshapen

Book a routine appointment if:

• If the pain has lasted for more than a few weeks
• If pain wakes you up at night or stops you from doing daily tasks
• If swelling keeps coming back
• If your knee feels unstable or gives way

Diagnosis

Your doctor will ask about your pain, any injuries, and how it affects your daily life. They will examine your knee, checking for swelling, tenderness, movement, and stability.

Tests that may be done

• X-ray – to look for joint space narrowing, bone spurs, or signs of arthritis
• Ultrasound – to check soft tissues such as tendons and fluid
• MRI scan – if your doctor suspects a tear in a ligament or the cushioning cartilage
• Blood tests – to help rule out inflammatory conditions like rheumatoid arthritis

What to expect at your appointment

You will probably leave with a plan to try simple measures first, such as activity changes, strengthening exercises, and pain relief. Scans are not always needed right away.

Treatment

Treatment for long-lasting knee pain depends on the cause, but most people improve with self-care and exercise. Your doctor will help you find what works for you.

Self-care at home

• Rest the knee, but keep moving gently to avoid stiffness
• Use ice for 10–20 minutes at a time to reduce swelling
• Support the knee with a tensor bandage or a knee brace if it helps
• Elevate the leg when you are resting
• Do gentle strengthening and stretching exercises – ask a physiotherapist for a plan

Medical treatments

Your doctor may recommend pain-relieving medicines (talk to your pharmacist about over-the-counter options), physical therapy, or in some cases, steroid injections into the joint to reduce inflammation. Always follow your doctor's advice and never take more than the recommended dose.

When is surgery considered?

Surgery is usually only considered if the knee is seriously damaged, or if other treatments have not helped after a good try. Procedures can repair or remove damaged tissue, and in very severe cases, the whole joint may be replaced.

Living with this condition

Think about the way you use your knee during the day. Place grip handles, avoid kneeling where possible, and take short breaks instead of standing for long periods. Small adjustments can make a big difference.

Lifestyle tips

• Keep a healthy weight to reduce pressure on the joint
• Stay active – moving regularly often helps more than staying still
• Choose low-impact activities like swimming, cycling, or walking on flat ground
• Wear supportive, cushioned footwear
• Use a knee support or orthotic if it feels helpful

Diet and exercise

A balanced diet helps you maintain a healthy weight, which reduces strain on your knees. Gentle exercise strengthens the muscles around the joint – the stronger your thigh muscles, the better they can support the knee. Low-impact options are easiest on the joint.

Mental health and emotional wellbeing

Living with ongoing pain can be frustrating and tiring. It can affect your sleep, mood, and confidence. It's important to acknowledge this and talk about it – your doctor or a counselor can offer support. Simple relaxation techniques, pacing your activities, and staying connected can help.

Prevention

You can't always prevent knee pain, but you can lower your risk by keeping a healthy weight, staying physically active, strengthening your leg muscles, and using safe techniques during sports and lifting.

Complications

If left untreated

• The pain may get worse and make daily activities harder
• The knee can become stiffer and less mobile
• You may lose muscle strength in your leg
• It may take longer to recover if a damaged joint gets worse

Long-term outlook

The outlook for long-lasting knee pain is positive for most people. With the right approach – including exercise, weight management, and simple pain relief – many people see big improvements. Even when the cause is chronic, you can still feel better and stay active.
