Has anyone experienced Achilles tendon problems from AI medication?

This sounds like a really challenging situation to navigate, and it's understandable that you're looking for others who might have similar experiences. Achilles tendon issues are indeed a documented side effect that some people experience with certain medications, so reaching out to this community to learn from others' experiences makes sense. Many members here have dealt with various medication side effects during their treatment journeys, and sharing these experiences can help everyone feel less alone while making informed decisions with their healthcare teams.

I'm dealing with similar issues and wondering the same thing - the walking difficulties are so frustrating and concerning. You're definitely not alone in experiencing these challenging side effects from AIs.

I am on anastrozole and last year developed achilles tendonitis, both ankles. I also have longstanding, severe osteoarthritis. I had been considering knee replacements and in January this year, I underwent one on my right knee. I have no more pain in my ankles. It’s possible the tendonitis was caused by gait changes due to my arthritis, and my gait has now improved . Ive also noted that my side effects from anastrozole wax and wane, change, come and go.

I’m finding going down stairs more of an issue. Not walking or going up stairs, just down the stairs. 🤔🤷‍♀️

Ruth, same with me before my knee replacement. The orthopedic said descending stair is more difficult for people with arthritis than climbing; knee has to bend more going down

My Achilles is one of my main complaints. Also ankles, wrists and fingers. And of course the fatigue!!!

The orthopedic doctor said the meds cause the tendons to widen. I am not wearing braces, so my feet stay at 90%. I go back this week. After a month of physical therapy one is better, the other is worse. The doctor said they can tear or rupture. If you are having problems, go see an orthopedic doctor right away. If it tears, you are looking at surgery.
