Because unless I want to go to urgent care or the emergency room (neither of which I think are a worthwhile idea), I cant even make an appointment to see my gyno until tomorrow.

I'm really sure it's not cancer because it must have shown up in the last 24 hours. Because of some chronic health problems I have (c-spine related), I massage my pectoral muscles a lot. Basically, when my neck muscles/back muscles get extra tight and messed up, it also causes tightness in the pectoral muscles. So all of it gets massaged (if you have upper back tension and/or sit in an office all day, massaging your pecs can actually help loosen you up as they usually get tight too and pull your shoulders forward).

Anyways, I've been having some bad pain for the last week or so, and I've been massaging my pecs daily, sometimes multiple times a day. I definitely gave myself a good massage after the gym on Friday. So this lump showed up sometime between Friday late afternoon and late last night.

It's almost directly under my nipple and it feels cone or disc-shaped, about a 1.5" diameter, maybe 1/4"-1/2" thick. The first thing I'm wondering is if something related to making breast milk somehow got infected. I've actually barely lactated for years. If my breast around the nipple gets squeezed hard enough, I will produce a little milk. I've had my hormones tested and they're normal, so it's just a random thing that I've had for at least 8 years, with no side effects. It takes enough pressure to happen that the chances of it happening by accident are pretty low, and it's not a lot of milk that is produced.

Anyways, I was wondering if anybody would consider non-cancer breast lump personal stories, if that's ok? I am really freaking out, and some support/"I had X and it worked out fine" messages would really help, I think.

First thing tomorrow, I'm calling my (awesome) gyno, but in the meantime, I could use a little support while I try not to freak out.
