Hi, I am 19 year old female and I have two pea size bumps right under my collar bone. One bothers me, even when my clothes seem to touch it, but the other does not. I am not sure how long they have been there, but the last two weeks, I have really noticed them. They are hard and seem to only move a little bit under the skin. They are under my collar bone, basically in the middle of my chest closer to my right boob.
