Similar- I was 60yrs. Stage 0 grade 2… tumor was 7mm, but DCIS was 4cm . My tumor was too small to do an onco score. Lumpectomy on left side, and reconstruction on both. 15 rounds radiation. I was also told that I needed the AI drugs. I had almost every side effect mentioned. If I was able to redo do anything- I wouldn’t have taken these. But at the time of treatment your( mine was) mind is in a different mode. I tried anastozole first- which put me in a chemical menopause- mental and physical nightmare, then Exemestane which was better but insomnia and joint/muscle point… I did and still do, acupuncture, healthy yoga and pranayama. I stopped taking them after about 2 1/2 yrs. I have been off for almost a year. I have arthritis in both hands and my left knee. I still stay very active- I recently went on GLP-1 shot ( lowest dose) it has helped with weight management ( I wasn’t huge, just chubby) which helps with joints and swelling and for me it makes me crave healthier food.
I know some people have no side effects from AI drugs and it depends on chances of cancer coming back. It’s a personal decision but a tough one. Blessings
