Pain is an uncomfortable feeling that tells you something may be wrong. It can be steady, throbbing, stabbing, aching, pinching, or described in many other ways. Sometimes, it's just a nuisance, like a mild headache. Other times it can be debilitating.
When your body is injured in some way or something else is wrong, your nerves (cells that help your body send and receive information) send millions of messages to your brain about what's going on. Your brain then makes you feel pain.
Answer:
When we feel pain, such as when we touch a hot stove, sensory receptors in our skin send a message via nerve fibres (A-delta fibres and C fibres) to the spinal cord and brainstem and then onto the brain where the sensation of pain is registered, the information is processed and the pain is perceived.
