How it relieves pain
Pain is caused by the stimulation of nerve endings. When the nerve endings are stimulated, sodium is enters the nerve ending, which causes an electrical signal to build up in the nerve. Once the electric signal becomes big enough, it is able to travel to the brain, which then interprets this as pain.
