Hi Pricey
I had to swap HRT earlier in the year and omg....my boobs, even something coming within a foot of them made them painful! It was slowly getting better but I managed to swap back to patches but still took a few weeks to settle down. That was on a pill progesterone which I never had with the patches.
Hopefully it will settle down! I think another couple of ladies on here said to try the Evening Primrose oil during this time.
Take care!
