RICE protocol... don't know if it's taught in NS...
RICE = Rest, Ice, Compression, Elevation
Be careful when doing compression... it may make things worse. The
main thing for first aid is to restrict movements and aid recovery,
but not making movements impossible.
For sprains, it happens because the joint twists too inwards or too
outwards. If the sprain is caused by twisting inwards (called
inversion sprain), you bandage it the other way round (meaning not
bandage it inwards, this makes things worse).
Think of it this way:
When something is out of place, you pushed it back in, not push
further out. Likewise, for inversion injuries, you don't bandage it
such that it twists more inwards.
