Hey, so I don't know how to start so I'm just going to go directly into the subject. I have something hard under the skin of my armpit. And it really hurts. At first it was small and it didn't hurt. But now it is big and painful. It hurts when i'm lifting my arm, even when I'm not doing anything. Also I have a pain in my chest, it feels like something acidic was pour in my chest. I know that you aren't doctors etc... But I would like to know if some of you had already experienced this.

If you need more informations: i'm 16 so I think that the risk of breast cancer is very low. Also I have this since 2 weeks ago. The reason I didn't talked about it is that it was very small at first, and that I had it before. But now it's way bigger than it used to be and it hurts. Also I have another “lump” above this one, but it's painless and it must be about the size of a pea. I'm going to show and ask my mom tomorrow, but I still want to know if I was the only one.

Thanks if you read that long text.😁
