Why do people put frozen peas on lumps or swollen parts of their body? I understand why we use something that is cold or frozen, but why peas? Does anybody know? Thanks
I would think because a bag of peas is flexible rather than a flat solid cold object, so you can lay it round your knee,etc. and not put too much pressure on the injury.
Alternatively, NICER ( as above plus non-steroidal anti-inflammatories). Peas are best, but if you've partially defrosted them, don't re-freeze and eat!
