How can I make a homemade ice pack?
assistant
To make a homemade ice pack, you will need some sort of container or wrap that is able to hold the water. You should also have a source for freezing your water. Once you have these things ready, fill the container with cold water and place it in the freezer overnight. In the morning, take out the container and let it thaw slightly before placing it on the affected area. Repeat this process every few hours until the swelling subsides.
