A new study of itch adds to growing evidence that the chemical signals that make us want to scratch are the same signals that make us wince in pain.
The interactions between itch and pain are only partly understood, said itch and pain researcher Diana Bautista.
The skin contains some nerve cells that respond only to itch and others that respond only to pain. Others, however, respond to both, and some substances cause both itching and pain.
