I have been on HRT now for over 5 years and my breasts these days are a small C Cup. Every couple of months one or other of my breasts (Aureole and Nipple) gets very sore and itchy. This tends to happen around the middle of the month. Over the last two months, its been the right breast, whereas about 4 months ago it was the left breast. It always appears to be just prior to me reaching my cycle. Basically I am on a 14 days Oestrogen only, then combined Oestrogen and Progesterone HRT mix for the last 14 days of the month. I take Oestrogen twice a day and Progesterone at night time before bed. At about 4-5 days after I start the combined dose, the nipple pain and itchiness subsides. Also 1-2 days before the cycle, I get very moody and seem to cry a lot. My BFF tells me its just the regular monthly cycle that women get, but of course that must be physiological!
