I began AI's with Arimidex and after a year and a half had to go off it due to painful joints, fatigue, and feeling ancient! next I tried Exemestane. i didn't really give it a fair trial, but began to feel the joint pain, so after a lengthy discussion with my Oncology N.P. I switched to Tamoxifen. I'm VERY interested to know what other people's side effects from Tamoxifen are. I've been on it for 7 weeks. Has anyone experienced severe itching and/or rashes?
