I've been on Arimidex/Anastrozole for nearly 12 months now - and am going fine. Tho a tad stiff, I don't have the excessive joint pains & trigger finger that I DID have on Letrozole and Exemestane.
Having said that - last night I was in excruciating pain for about 10 mins when (at about midnight) my left leg went into 100% spasm - it seemed that every single muscle & cell from the knee down was bouncing off each other! It was all I could do not to scream in pain! I was actually wondering how long I 'leave it' til calling 000! If I moved my leg 1cm - it made it worse - leaving it where it was made it worse ..... I was almost in tears.
This is the first time this has ever happened - and I seriously feel sorry for anyone who is in pain 24/7 - cos 10 mins of this was bad enough!
Then it stopped! I just hope it doesn't return - as it was truly horrible. I do not know what caused it.
Take care, stay safe & well xx
