Please contact your doctor immediately if you haven't as jaw pain could be an early sign of osteonecrosis, i.e., dead bone of the jaw. For which there is no cure or treatment. Prolia is a drug that shares that not-common side effect. [I personally think that Prolia shouldn't even be sold here because the side effects are so nasty. And it's only been around for 10 years so there are no studies of long-term, yet alone permanently-damaging, consequences of using it.]

There are alternatives though, as I'm sure you know, none of them are perfect. It's just that some have lesser risks or risks that can be monitored for and avoided at first sign of any issues.
