Hi Linuk - no real advice I'm afraid but I just wanted to welcome you.
You may find that you get more replies if you begin a new thread under All Things Menopause or New Members and title it Breast Tenderness Kliovance. How long have you been taking the Kliovance for?
You will find lots of help, advice and friendship on here and there are other HRT's for you to try if the tenderness doesn't settle down so don't be despondent.
