Short answer: heat or cold for knee pain depends on the knee: cold for a new, swollen or flared-up knee; warmth for old, stiff, aching knees.[4][5]
Heat or cold for knee pain: what to know
- Cold: up to 20 minutes every 2 to 3 hours, wrapped in a tea towel, never on bare skin.[1]
- Warmth: a warm pad or bath for around 15 to 20 minutes for ongoing stiffness. Avoid heat right after a new injury, and avoid it when the joint is already warm and swollen.[4][5]
- Both: many people use warmth before gentle exercise and cold afterwards.[5]
- Take care with burns if you have reduced feeling in the skin, for example with diabetes.
Warmth you control
Warmth that you control is the whole point of the handheld devices we show at our centre: a gentle stream of warm air with settings you can change. If you'd like to feel it first, the first session is complimentary.
When to see a doctor
If it isn't improving after a few days of home care, or it's getting worse, see a doctor.[5]
