Osteoarthritis is the most common form of arthritis, occurring when the protective cartilage that cushions the ends of bones gradually wears down over time. This leads to joint pain, stiffness, and swelling, most often affecting the knees, hips, hands, and spine.

What is Osteoarthritis?
Osteoarthritis is the most common form of arthritis, occurring when the protective cartilage that cushions the ends of bones gradually wears down over time. This leads to joint pain, stiffness, and swelling, most often affecting the knees, hips, hands, and spine.
It tends to develop gradually with age, though injury, joint overuse, excess weight, and genetics can all increase risk. Symptoms often come and go, sometimes flaring up with activity or changes in weather, and typically ease with rest.

Clinical context
Self-care advice
See your GP if joint pain is persistent or worsening, so a management plan including exercise, pain relief, and possibly physiotherapy can be put in place.
03 · Act
When to see a doctor
- 1Joint pain or stiffness is persistent, worsening, or affecting your daily activities
- 2A joint becomes suddenly red, hot, or significantly swollen
- 3Pain is disturbing your sleep on a regular basis
- 4You're finding it increasingly difficult to walk, grip objects, or manage everyday tasks
- 5Over-the-counter pain relief is no longer providing enough relief
04 · Prevent & manage
Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Stay active.Regular, low-impact exercise such as swimming, cycling, or walking helps keep joints mobile and strengthens supporting muscles.
- 2Maintain a healthy weight.Reducing excess weight lessens the load on weight-bearing joints like the hips and knees.
- 3Use heat or cold as needed.Heat can ease stiffness, while a cold pack can help with acute swelling after activity.
- 4Take pain relief when needed.Paracetamol or anti-inflammatory medication, used as directed, can help you stay active and comfortable.
- 5Consider physiotherapy.A physiotherapist can suggest targeted exercises to strengthen muscles around affected joints and improve function.

BarnMD Bottom Line
Osteoarthritis can't be reversed, but staying active and managing weight and pain effectively can significantly slow its impact on daily life.
Movement is medicine for osteoarthritis — gentle, regular activity protects joints far more than rest does.
