Make "gel" ice pack yourself
Many ice packs are impractical because they are hard frozen and not so flexible.
Ice gel bags filled with gel are best, but if you do not have them, you can easily make yourself that way.
Recently, I wanted to cool my knee a bit. It is good to use a flexible ice bag, which adapts to the contours and since I have not found an ice pack, I filled a freezer bag with detergent (a little more Spüli) and then frozen.
After one hour, the bag was well cooled and super flexible. Since detergent can not freeze, this is a very good solution and a good alternative to a bag filled with gel.
Now I leave the bag with Spüli in the freezer for the next use.
