Little is known about why we itch. Sometimes we can see a cause, such as a scab or an insect bite. Stimulating pain receptors can cause itching, but no nerve-endings have been specifically connected with itching alone. Thinking about an itch can bring on the urge to scratch, but the reason for this is a mystery.
