There are lots of different things it could be.  I've had cysts, mastitis and lots of other things over the years. Easy to say but try not to let your imagination run away with you.  We all tend to think the worst, it's sometimes human nature.  Best thing you can do is get to the appointment next week and find out what's going on with you.  Consultants at the breast clinic see hundreds of people per month so have so much experience in diagnosis.  Some will need further investigation and others won't as the cause of the problem will become more obvious once they've run some tests.  Good luck on your visit and hope everything works out for you.

Hi

How did your appointment go, I hope everything came back clear
