What do you know about Montgomery's tubercles (areola bumps)?

Montgomery's tubercles are those bumps on the areola. Do they ever swell outside of pg?

My breast and nipples have been super sore since 1dpo, and since my cycles have been wacky since my loss and surgery last year I was wondering if this might be just hormonal imbalance and not pg.

The only time I had ever seen my nipples look so weird was when I was pg. I'm not sure what happened this last cycle but it is possible that my body just produced way too much of one of the estrogens -- like maybe I produced more estrone than normal. A day after I posted that the syptoms had subsided so it was just a fleeting thing.
