What Are the Early Signs of Osteoarthritis?

Learn about the early signs of osteoarthritis, including joint pain, stiffness, swelling, and changes in movement, and when it's time to talk with a healthcare professional.

A little stiffness in your knees when you get out of bed. A sore hip after a long walk. Fingers that don't seem to move quite as easily as they used to.

These things can happen for many reasons, and they don't automatically mean you have arthritis.

But when joint pain or stiffness keeps coming back, it's worth paying attention to what your body is telling you.

One possible cause is osteoarthritis, the most common form of arthritis. It happens when the tissues inside a joint gradually change and break down over time. It is more common as people get older, although younger people can develop it too. (NIAMS)

So what should you look out for?

1. Joint pain during everyday activities

One of the most common signs of osteoarthritis is pain when you use the affected joint.

You might notice it when walking, climbing stairs, getting up from a chair, opening a jar, or doing another activity that involves the joint.

The pain can be mild at first and may come and go. Over time, however, it can become more noticeable or start interfering with things you normally do.

Osteoarthritis commonly affects the knees, hips, hands, neck, and lower back. (NIAMS)

2. Stiffness after resting

Have you ever sat for a while and then felt stiff when you stood up?

Short periods of stiffness can happen with osteoarthritis, particularly after sleeping or sitting still for some time.

For many people with osteoarthritis, morning stiffness lasts less than 30 minutes and gradually improves as they start moving. (NIAMS)

That doesn't mean every episode of morning stiffness is arthritis. There are many possible causes of stiff joints.

What matters is whether it keeps happening and whether it's accompanied by other symptoms.

3. Swelling around a joint

Another possible sign is swelling in or around the affected joint.

You might notice that one knee looks slightly different from the other or that a finger appears thicker than usual.

Swelling can have many causes, so it isn't enough by itself to tell you that you have osteoarthritis.

If swelling continues or keeps returning, it's worth having it evaluated rather than trying to guess what's causing it. (NIAMS)

4. Your joint doesn't move as easily

You may notice that a joint doesn't move as freely as it once did.

For example, your knee might feel harder to bend, your hip may feel less flexible, or your fingers may not move as easily.

These changes can happen gradually, which means you may not notice them immediately.

Sometimes you only realize something has changed when an everyday task becomes more difficult.

5. Your joint feels weak or unstable

Some people with osteoarthritis feel as though a joint is less stable than it used to be.

A knee, for example, may occasionally feel like it could buckle or give way.

This can happen as changes in the joint and surrounding muscles affect how well the joint functions. (NIAMS)

If a joint repeatedly feels unstable, it's a good reason to talk with a healthcare professional.

Does joint pain always mean osteoarthritis?

No.

This is important because joint pain can have many different causes.

An injury, another type of arthritis, repeated stress on a joint, or other health problems can cause similar symptoms.

Even osteoarthritis itself can look different from one person to another.

That's why symptoms alone can't confirm a diagnosis.

A healthcare professional may ask about your symptoms and medical history, examine the affected joint, and sometimes use imaging or other tests to understand what's happening. (NIA)

Can you do anything to support your joints?

If you're noticing mild stiffness or discomfort, staying physically active is generally an important part of maintaining joint health.

That doesn't mean you need to start an intense exercise program.

Walking, swimming, cycling, water exercise, and tai chi are examples of lower-impact activities that can help you stay active while putting less stress on your joints. (NIA)

Strength exercises can also help because stronger muscles support the joints and can make everyday movements easier.

If you haven't exercised in a while, start slowly and gradually increase your activity.

What about your weight?

Your weight can also affect your joints, particularly your knees and hips.

These joints carry much of your body weight throughout the day. For people who are overweight and have osteoarthritis, losing weight can reduce stress on the joints and may improve pain and mobility. (NIAMS)

This doesn't mean you need to make drastic changes.

A balanced diet and regular physical activity can be a more sustainable approach than trying to lose weight quickly.

When should you see a healthcare professional?

You don't need to panic every time a joint feels stiff or sore.

But it's a good idea to get persistent symptoms checked, especially if they are becoming more frequent or starting to interfere with your everyday life.

Consider talking with a healthcare professional if you notice:

Joint pain that keeps coming back
Stiffness that is becoming more noticeable
Ongoing swelling
Difficulty moving a joint
A joint that feels unstable
Pain that makes everyday activities difficult

Getting an accurate diagnosis can help you understand what's causing the symptoms and what options may be appropriate for you. (NIAMS)

The bottom line

Osteoarthritis often develops gradually, so the first signs can be easy to overlook.

A little stiffness or occasional joint pain doesn't necessarily mean you have osteoarthritis. But if those symptoms keep returning, become worse, or start changing the way you move, it's worth paying attention.

Staying active, maintaining a healthy weight, and taking care of the muscles that support your joints are useful parts of looking after your mobility as you get older. (NIA)

And when you're unsure about what's causing your symptoms, getting professional advice is better than trying to diagnose yourself.
