My left breast has been hurting on and off for about a month now. I have fibrocystic breasts, and it really can mess with your anxiety. Just had my 6-month "breast checkup" (I'm high risk so I have a whole screening schedule) and the nurse said everything felt normal, so probably just hormones doing their thing. My breasts are so lumpy that monthly self-checks are just kind of
. I just kind of try to find evidence of a hard or fixed lump, and figure all the softer lumps are cysts or fibrous breast tissue.
Sounds like you are on the right track with this. If your node is shrinking at all, that's a good sign that it's just doing normal lymph node stuff. My own lymph nodes are annoyingly reactive--any little thing sets them off, so I've had to force myself not to go prodding at them.
