Anastrozole Withdrawal

I stopped anastrozole after 5yrs and some pretty rotten side effects.  Also I got to my 5yr anniversary.  Lately I ha e developed joint pain in my leg, more so hip and knee.  Which is what I had going in to anastrozole.  I can’t see any information about side effects coming off it.  Does or has anyone who is off it experienced this.  It’s sort of like in reverse etc. 

Sounds miserable  . I didn’t have much impact coming off tamoxifen but I had a lot of other health issues at the time so maybe I didn’t really register them. 
you could ask this question in the ask the nurses section ?
