If you mean 7 warning signs that could indicate arthritis and deserve medical attention, here’s a detailed guide. Arthritis is a broad term covering more than 100 conditions, so symptoms can vary considerably.
7 warning signs of arthritis you shouldn’t ignore
1. Persistent joint pain
Pain in a joint that keeps coming back or lasts for several weeks is one of the most important warning signs.
Arthritis pain may:
- Affect the knees, hips, hands, wrists, feet, shoulders, or spine.
- Be worse after activity in osteoarthritis.
- Be present even when you’re resting.
- Affect several joints at once in inflammatory forms of arthritis.
- Gradually become more frequent or severe.
Occasional soreness after unusual exercise isn’t necessarily arthritis. Persistent or progressively worsening pain is more concerning.
2. Joint swelling
Swelling around a joint can occur when the tissues lining or surrounding the joint become inflamed.
You might notice:
- A visibly enlarged joint.
- Rings or shoes suddenly becoming tighter.
- Puffiness around the fingers, wrists, knees, or ankles.
- A feeling of pressure or fullness inside the joint.
Repeated or unexplained swelling deserves evaluation, particularly if multiple joints are involved.
3. Morning stiffness that lasts a long time
Pay attention to how your joints feel when you wake up.
A few minutes of stiffness after getting out of bed can occur with normal aging or osteoarthritis. But morning stiffness lasting around 30 minutes or longer, especially when it occurs regularly, can be a sign of inflammatory arthritis.
Stiffness that improves somewhat as you start moving can be particularly characteristic of inflammatory joint disease.
4. Reduced range of motion
If a joint gradually becomes harder to move, don’t simply assume it’s part of getting older.
Examples include:
- Difficulty making a fist.
- Trouble bending or straightening a knee.
- Difficulty climbing stairs because a knee or hip won’t move normally.
- Losing the ability to raise an arm overhead.
- Difficulty turning a doorknob or opening jars.
Loss of mobility can occur because of inflammation, cartilage damage, pain, swelling, or structural changes in the joint.
5. Warmth, redness, or significant tenderness around a joint
An arthritic joint may become warm, swollen, and tender, particularly during an inflammatory flare.
This is especially important when symptoms appear suddenly.
However, a hot, red, extremely painful joint accompanied by fever or feeling very ill is not something to assume is simply arthritis. A joint infection can produce similar symptoms and requires urgent medical assessment.
6. Symptoms affecting both sides or multiple joints
The pattern of symptoms can provide an important clue.
For example, persistent symptoms involving:
- Both hands or wrists.
- Several fingers.
- Both feet.
- Multiple joints simultaneously.
may suggest an inflammatory form of arthritis rather than a problem caused by a single injury.
Some autoimmune types of arthritis can also cause symptoms outside the joints, such as unusual fatigue, fever, skin changes, eye inflammation, or unexplained weight changes.
7. Joint symptoms that progressively interfere with everyday life
Perhaps the most important warning sign is a gradual loss of normal function.
Consider getting evaluated if joint problems are making it difficult to:
- Walk normally.
- Go up or down stairs.
- Dress yourself.
- Grip objects.
- Work or exercise.
- Sleep comfortably.
- Perform household activities.
Arthritis can progress over time, and identifying the specific type early can help determine appropriate treatment and prevent avoidable loss of function.
When should you seek medical attention?
Make an appointment with a healthcare professional if you have persistent joint pain, swelling, stiffness, or reduced movement, particularly if symptoms are worsening or affecting multiple joints.
Seek urgent medical care for a joint that suddenly becomes extremely painful, swollen, hot, or red—especially if you also have a fever or feel seriously unwell. Those symptoms can indicate an infection or another condition requiring prompt treatment.
One important point
Not every painful joint is arthritis. Gout, bursitis, tendon problems, injuries, infections, autoimmune diseases, and other conditions can produce similar symptoms. A clinician may need to examine the joints and, depending on the situation, order blood tests or imaging to determine the cause.
