Bump on breast

[tlmccan]

I have a quarter size purple lump on right breast below and to the left of areola. It has hard core and very painful. Just went to dr and he said it was infected montgomery follicle \, I thought those were actually around nipple on areola, this is way below there. Can it still be montgomery follicle that low? Is it a hormonal cyst?

Dear tlmccan:  Montgomery's glands are usually on the areola - but they can be anywhere on the areola - not necessarily right next to the nipple.  Anything can technically become infected and we don't always know how.  Infections can occur from irritation, ingrown hairs and a variety of other causes.  Without evaluation, it is impossible for us to speculate on whether this "bump" is an infected montgomery's gland or what it might be.  If it does not improve with the warmth and bactrim, you should let your doctor know because additional evaluation may be needed.

This is not a pimple, it is a huge cyst like thing that the doctor called infected montgomery follicle. it hurts very bad, told me to put warmth on it and gave me bactrim for it, if it does not go away he mentioned surgery. what causes this to get infected?
