I've been taking Tamoxifen for just over 5 years. I had a Lumpectomy, radiotherapy . It was grade 2 and not in my lymph nodes. About 18 months ago I was diagnosed with Sacroiliitis . Since then the pain has become progressively worse. I recently read an article which indicated that it is possible that my Sacroiliitis can be related to taking Tamoxifen. I know that in the last 10 years there had been a move from the need to take it Tamoxifen for 10 years rather than 5, I was advised to take it for 10. Im looking for advise on whether  or not there is a significant risk in stopping Tamoxifen to improve my quality of life. My Sacroiliitis means I am in constant pain and finding day to day activities difficult.

many thanks
