BRUISE - Bleeding under skin
Why?
Because of impact
Rx - Cold pack
1. Method1 - Take any empty flat plastic bottle like savlon, fill it three quarters with water & freeze. This can be used as a cold pack
2. Method2 - Take a clean kerchief, drench with cold/running water. Squeeze out extra water & use as cold pack
SWELLING - Due to hurt
Why?
When there is a hurt, the body's defense mechanism - WBCs go to the hurt area, causing a swelling.
Pain is caused when nerves under skin get pressed
Rx - Cold pack
