Remember to never place ice or heat directly on your skin. Use a barrier, like a towel, to protect your skin from a burn.
How long you use ice as a treatment can depend on the painful area but generally up to 15 minutes leaving a few hours between treatments.
You should stop treating the area with ice or heat and seek advice from a medical professional if you notice an increase in redness, discolouration or blistering of the skin.
If you have any issues with circulation or sensation, you shouldn't use ice or heat as a treatment for back pain.
