Hi,my name is Ruben,i,m "" years old and quite a healthy life....no allergies,muscular problems and i don,t use to get sick; i do have a greasy skin and i have notice that i do have several grass small lumps behind both ears.didn,t grow much yet but i can feel like i do have cartilage balls.....it could,d be something to do with any organ malfunction or grassy alimentation? Thanks in advance
