Hello!
I have suffered with hormonal breast pain for about 3 years. It's hot (yes, you could say burning) and is generally on the upper outer side. It kind of radiates out to my armpit.
I am a massive breast cancer-phobe (sister had it in her 30's and maternal aunt, mother's twin) and the breast pain feeds my anxiety. I'm literally conscious of my boobs all the time, checking for lumps, etc etc.
I have my breasts checked regularly and I'm always very anxious and convinced that the pain means something awful.
My consultant says it's hormonal, common (particularly with big dense breast like mine). He says take starflower oil every single day.
Please try and not worry. Trust your doctor and be confident and happy that she is covering all bases, just in case.
When mine is terrible, ibuprofen can help.
I always wear a bra by the way, 24/7.
There is a good section on breasts on the 34 menopause symptoms website. Go and have a read xxx
