Hey so I found this lump ages ago, I didn't really think anything of it but it keeps playing on my mind now , I do have health anxiety and it's at the bottom of my sternum sort of level with my breast bone, it's movable and sore! Not sure if it's grown at all. Im 22 mother of 1 and am terrified to say the least, I will book a doctors appointment but im dreading if anyone know what it could be ðŸ˜
