Here is another link to a paper published concerning problems caused by aromatase inhibitors. I was also diagnosed with Bilateral DeQuervain's tenosynovitis in 2014 and after being taken off Arimidex, a few months later it started getting so much better and then it completely resolved. I am so glad my doctor recognized it because it also settled in my other joints and I was vert miserable. I then went o tamoxifen. Oddly, when more tumors popped up, a biopsy showed that I am now ER- so I was also taken off Arimidex. Never know what to expect! Best of luck and here's the link to a case study on one woman:
