Bought this for strained lower back. I can alternately use it as a cold pack, then a warm pack, then freeze it again to use cold etc. The bag of peas I was using could handle the cold ok for about a weeks worth of use. This should last indefinetly.
For Heat Therapy: Wrap pack with damp cloth or paper towel. Microwave for 30 seconds, add additional 5 second intervals until desired temperture is reached.
For Cold Therapy: Freeze for at least 2 hours. TheraPearl should only be applied to the relief area for the doctor recommended time of 20 minutes.
TheraPearl Care: Packs can be cleaned with a mild soap, detergent or alcohol. Do not place any heavy objects on top of your packs. Discard pack if punctured. Do not swallow beads. Do not use on infants.
