I am a male at the age of 20 and have noticed that my right nipple is drastically larger then my left nipple. I have excruciating pain when it is bumped or rubbed. And have dark yellowish green liquid coming from it when I squeeze. Its been like this for about a year and hasn t gone away, what could this be, and what could I do?
Thanks for asking in Chat Doctor forum In short: You have an infectionExplanation: Sometimes, asymmetry can occur congenitally. So, you need not worry about asymmetry. But if you are having any discharge from the nipple then it is infected. Please visit a doctor to get yourself examined for this.  If it is milk, it might have caused due to Chat Doctor.  It can occur in males too. Hope this will help you. Do not meddle with it.
