I was diagnosed and had a mastectomy 3 yrs ago. I had radiotherapy and was prescribed letrozole. I get lots of the side effects....eg...muscle pain and weakness, sleepless nights ..irritability...mood swings...depression...the list goes on. However, the one thing that upsets me so much is the inability to show or give my husband affection. My libido has diminished due to dry /atrophic vagina. Any attempts to have intercourse is just far too painful. I've tried lots of different moisturisers. Anyone else suffering?
