Hi, I m a 19 year old female. 5 7, 120 lbs. Throughout my teens I ve been having some pain in my left breast, not so much in my right one. Now noticed that the pain is usually in my left side of the left breast. It s sometimes sharp. Also, my right breast was always slightly larger than the left one. It s also softer. However I don t feel any lumps in the left one, just a thicker consistency. I was wondering if there might be something wrong with me.
