Why Peas?

[Gulyasgirl]

Why do we put frozen peas on lumps or swollen parts of our body? I understand why we use something that is cold or frozen, but why peas? Does anybody know? Thanks

It's because, as well as being frozen, the package is pliable, so you can ensure it 'molds' to the area you want to chill - any other frozen package is either in a box, or too solid to use in this way.

and also because it's something that's quite likely to be found in your fridge. You can get proper ice-packs, but most people don't have one when they need it.
