@nwyatt I am curious how osteoporosis and fractures could cause arthritis. I think of them as separate entities.

Evenity inhibits sclerostin. People with osteoarthritis and rheumatoid arthritis have low sclerostin naturally, so low sclerositin is associated with these issues. It is possible therefore that Evenity could cause or exacerbate arthritis of both kinds, though whether that is temporary or permanent has not been determined. One doc told me that 40 % of his Evenity patients have joint pain. It is a new drug but I personally hope that any effects are short term and it seems the pain fades, from various posts on forums.
