Joint pain: causes, warning signs & what to do
Aching or swollen joints can come from wear, injury, gout or an autoimmune condition. The pattern — which joints, morning stiffness, swelling — points to the cause.
Common causes of joint pain
- Osteoarthritis — wear-and-tear, worse with use, in older adults
- Rheumatoid arthritis — symmetrical, with prolonged morning stiffness
- Gout — sudden severe pain, often the big toe, red and hot
- Injury or overuse (sprain, tendinitis)
- Viral infections causing temporary joint aches
- Lupus or other autoimmune disease
When to see a doctor urgently
- A hot, red, very painful swollen joint with fever (possible infection) — seek urgent care
- A joint that cannot bear weight after an injury
- Joint pain with a widespread rash or feeling very unwell
- Prolonged morning stiffness (over an hour) in several joints
Frequently asked questions
Is my joint pain arthritis?
Possibly — osteoarthritis worsens with use and age, while rheumatoid arthritis is symmetrical with long morning stiffness. Blood tests and an exam help tell them apart.
What makes gout flare up?
High uric acid crystallising in a joint — often triggered by alcohol, red meat, seafood or dehydration. A sudden, very painful big-toe joint is classic.
