Is it possible to get tendonitis from taking an anti estrogen? I have been on el1minate for about 6 weeks now. Joints were slightly sore but about 2 weeks ago after playing baseball and then going to the driving range my right elbow started screaming. I'm assuming its golfers elbow from hitting baseballs and golf balls all day. I've never had it before and was wondering if it could have came on since I was low on estrogen. I have played golf and baseball for years and never had this
