Can I use the heat if my knee is swollen?
Updated October 25, 2026
Do not use heat on a swollen knee. Get prompt medical advice if the knee locks, gives way, swells markedly, cannot take weight, or hurts very badly. Get urgent care for a hot, red, swollen joint with fever.
Even if you've used it, you can return it within 45 days of delivery at no cost to you — if we need it back, we email you a prepaid US return label.
