My mom was on anastrozole for 5.5 years after a DCIS with no spread and she has permanent arthritis now, memory loss, high blood pressure and cholesterol which she did not have before. She did not notice any side effects while taking them, but when she stopped it became more obvious what her possible side effects are. It's so hard to say if it was the anastrozole or not but those are her symptoms. I'm on tamoxifen as I had toxicity with the AI's confirmed by my Onco, so I'm struggling with hair loss and would love ideas as to how to try and lose less if it's possible while still taking tamoxifen.
