I'm sorry you suffer from so many side effects! I agree that you need to talk with your onco to see if there's benefit in taking AI. You might want to switch to exemestane to see if it's tolerable. I had severe finger stiffness, pain on my foot and collar bone, high triglycerides while on anastrozole. My onco switched me to exemestane, the finger stiffness got a lot better, the pain is more tolerable, and my triglycerides drops to under 100.
