sore breast!

hi all ..... I've had sore tender breasts before in my life, most women have.
But since starting perimenopause about 2 yrs. ago, i now have yet another wonderful symptom of this time in life...my left breast is hurting! It's only the left one.
This started about 5 days ago, out of nowhere. I had a breast exam on June 9th, and all was fine. Most of my friends who are in peri, have had trouble with this as well, but I'm wondering if there is any kind of herb i can take, that can help with this.
I know EVENING PRIMROSE OIL can help, so I'll be getting that tomorrow. Is there anything else?

Also, after shaving under my arms 4 days ago, i noticed (2 days ago) that, that gland, or muscle (or whatever that is that is under the armpit, that sort of winds downward and goes around to your back), was swollen, and ON it was this little "bump", which is sore. UGH! one thing after another! I think it's an ingrown hair follicle from shaving, this happ. to a friend of mine, and she had almost the same thing, she had this little bump under the skin, and it was sore, just like mine. The only diff. with me, is that, under this bump, the entire gland (i guess that's what it is) is swollen, which, i was told, is from that ingrown hair thingy! It's gotten better since yesterday, but it's still there, how long does that take to go away? What can i put on there to help it? It bothers me somewhat, and kind of makes the underarm area ache slightly. (when i move my arm up, it almost feels as if the skin udner there were "tight", or "stretching") ....

well, thank you all for any help you can give me!!!!
