Concerned about the side effects of anastrozole

I had osteopaenia going in to treatment, and my experience(s) while on Anastrozole for 7 months, including my left knee totally blowing out and putting me in a wheelchair for 6 months, has led me to the very likely conclusion that the knee collapse (of an already fragile joint) was exacerbated by Anastrozole. I started out with the intention of being treated, start to finish, by Genesis in Davenport, given very bad interactions at Trinity in Moline since 2018. I wouldn't even go to Trinity for a simple mammogram after 2018, but the pandemic upended my plans to avoid the Illinois side of the river and the 33 radiation treatments I was told I needed, which was a fairly lengthy process, as you can imagine, did not help, so, having been told that I didn't even need an oncotype, I interpreted that to mean that my b.c. was a garden variety tumor that could just as easily be treated locally. Not sure that was a wise decision, but it is why I ended up back at Trinity and not at Genesis, where I had already selected a surgeon (Dr. Hartmann), who, among other pandemic crises, totally disappeared without a word to the patient(s) as to where he had gone or when he would be back. (It was very weird that those of us whom he was supposed to operate on were not told anything about the sudden cessation of his office. Since I had done some reading on optimal times to have surgery and knew that simply "hanging around" for months wasn't ideal, I tried to be positive and gave in to the idea of going to the much-closer Trinity for the radiation, despite bad experiences there during a breast biopsy in 2018. The reason I have not gone forward with more active treatment for bone loss is that I am "borderline" currently and the discussion(s) on taking biphosphanates (among other things) and on the veracity of Dexa scans are everywhere. With a T score of -2.2T currently, I filled, but did not take, such a pill. It was prescribed me by my endocrinology team at my request. I was told to step up my calcium intake (with D and K) and did. (There is some information out there about whether or not an uptake in calcium can contribute to heart attacks and strokes, so taking 600 mg. in the morning and 600 mg. at night is about all I've done, so far. My next trip in to see the endocrinology team is in early May. Meanwhile, I've been locked into major dental work ($10,000) since November and was glad I could truthfully say I had not taken the biphosphanates that they feared might weaken my jawbone prior to their implant procedures.

I understand the need to avoid certain drugs while undergoing dental procedures; I postponed Prolia for a year for similar reasons. As to calcium supplements, I recently read an article by the Cleveland Clinic which shares the heart concerns for too much calcium in the blood. However, that's only if using supplements as opposed to the many calcium sources in our food which can have the opposite effect.

It is so complicated! I took have osteopenia and on Anastrozole. I had Prolia shots in 2019 and massive dental work in early 2021. Luckily everything went well.
I had been in fosamax in earlier years, but my jaw bone was good.
So many things we have to balance now that I never worried about before. I understand what you are saying.
Right now for me it's fatigue. Really struggling.
