Do Bones Have Feelings?
No, bones themselves do not feel pain or other sensations. However, the periosteum, a membrane covering the bone, is richly supplied with nerves. These nerves detect pain, pressure, and other sensations, which are often misinterpreted as pain in the bone itself.
- Periosteum's Role: The periosteum, a tough membrane covering bones, contains a dense network of sensory nerves. These nerves transmit signals related to pressure, injury, and inflammation to the brain. This is why bone fractures are intensely painful – it's the damage to the periosteum and surrounding tissues, not the bone itself, that causes the sensation of pain.

- Bone Matrix: The bone matrix, the hard substance of the bone itself, lacks the neural tissue needed to feel. Source: Reddit - Do we actually feel pain in our bones? If yes, how?
- Pain Perception: While bone itself can't feel, pain experienced during a fracture or bone disease arises from the damage to the surrounding structures like the periosteum, blood vessels, and muscles. Source: GoodRx - Does Breaking a Bone Hurt? 3 People Describe the Feeling
Bone Pain: A Misconception
It's crucial to differentiate between pain in a bone and pain associated with a bone. Often, pain perceived as being "in the bone" actually originates from the surrounding tissues and nerves. Bone cancer, for example, can cause severe pain, but this pain is largely due to the tumor's pressure on nerves and surrounding tissues, not a sensation within the bone structure itself.

In summary, bones lack the sensory receptors required to experience feelings directly. The sensation of bone pain is primarily attributed to the stimulation of nerve fibers in the periosteum and surrounding tissues.
