@vmcgrantham, endocrinologist and rheumatologists have specializations. Even though both disciplines treat osteoporosis, it is really difficult to stay on top of research and protocol for even one malady. Rheumatologists seem to specialize in autoimmune spectrums which is vast. Endocrinologists seem more vested in diabetes and thyroid disorders. Some few specialize in osteoporosis.
Your rheumatologist may feel a little put upon to handle osteoporosis. I see osteoporosis as primarily an endocrine disorder and would fall under the endocrinologist purview.
Forteo is definitely a money maker.
Forteo and Tymlos build the best most integrated most flexible--able to bear impact without fracture bone. Usually they are the most expensive osteoporosis medications, which is the reason why you can't get Forteo through the public health system unless you've had a fracture. And you can't get Tymlos In the [UK public healthcare system.}
Your endocrinologist might be happy to treat your osteoporosis. Maybe call the endocrinologist's office and ask staff if they treat osteoporosis.
