During a massage, the skin and fingers create friction. Friction encourages blood flow to increase. Oxygen and nutrients -which are essential for the repair of damaged muscle fibres- are carried within the blood flow. Increasing blood flow increases the rate of healing that helping to reduce the pain. The friction created between the skin and fingers, also creates a new sensation. The new sensation is picked up by the receptors within the skin, disturbing the signal sent to the brain. Disturbing the signal sent to the brain means fewer messages are sent to nerves to create a feeling of pain. A new message encouraging relaxation and decreased pain is sent to replace the original message. Disturbing the signal sent to the brain therefore reduces pain.
