Yes, bones do have pain nerves, specifically within the periosteum (the outer covering of the bone) and the bone marrow cavity.
These nerves are called primary afferent neurons and are responsible for transmitting pain signals (nociceptive information) from the bone to the central nervous system. This allows us to experience pain originating from the bone itself. While the hard, mineralized part of the bone has fewer nerve endings, the periosteum is richly innervated, making it a significant source of bone pain.
In summary, both the outer and inner bone structures possess nerve fibers that are capable of transmitting pain signals.
