I'm worried.
I've had a pain in my left breast for a few days, its getting worse, but not unbearable.
I've had a look and feel, and today i think it's a vein right by my nipple, and the nipple is painful too. I can't feel any lumps.
I haven't breastfed for nearly 2 years. What could it be? Have phoned gp and hold atm.

Any chance you've knocked it in the last few days? I got a painful lump that took a couple of days to appear after slipping by the bath. It could be an infection, but highly unlikely to be cancer as that won't present with sudden pain like this.

No, I've not knocked it at all. Thanks for the reassurance.
