Use the cold water therapy device as directed by your healthcare provider. They will tell you how many hours a day you should use it.

Apply the pad to the area of your body that is injured. Do not apply directly to your skin. Use a cloth between the pad and your skin. Don’t wrap the area too tightly. Firm pressure is enough.

Press the hand pump several times as directed. You will feel cold water fill the pad. Some newer devices have an electronic pump and don't need a hand pump.

Pump again whenever the pad starts to feel warm (15 to 20 minutes). You can continuously circulate the cold water from the cooler. Some newer devices automatically circulate the cold water. They don't need manual pumping. Most devices can provide several hours of cold therapy.

Check your skin under the wrap often and keep your skin dry.

Take pain medicine as directed.
