Itch is a sensory stimulus to our body. If a fly happens to sit on your arms or a mosquito is about to bite you, you have the feeling of itch. It is, you might say, a modified form of the touch sensation. This sensation persists till you remove the source stimulus by scratching or rubbing. Too mutch scratching may also lead to pain, which is believed to inhibit the sensation of itch.
