K.,
Welcome to mamapedia - are you pregnant? Are you nursing? Have you received trauma to your breast lately?
Have you called your doctor and told them what is going on?
Have you SEEN a doctor and been examined???
HOW LONG HAS THIS BEEN GOING ON??
How old are you?
So many unanswered questions. If you're having pain? I'd call my advice nurse and ask if I need to be seen.
Good luck!
