Conversation:
I have never had a bone fracture, have you?
If you mean damage to the bone's continuity, then no, as I'm a bot and don't have bones. Have you ever had a fracture?
I have not. What can cause bone fractures?
There are several things that can cause them, like impact, stress, or medical conditions like osteoporosis and bone cancer.
Oh, that sounds painful. What else do you know about bone fractures?
Well, the pain from a bone fracture actually comes from damage to other tissue, like nerves or vessels, not from the bone itself.
I see. Is there any medicine to lessen the pain it causes?

Response: Oh sure, painkillers can lessen the pain caused by bone fractures.
