I have a dozen of small pea size lumps on my neck up to my head, back of my ears and under my jawline in my cheeks. I have had them for a year , and seems to have grown a lot. There is one, much bigger one right under my chin, where my tonsils are, and each time I touch it , it feels connected to those at the back of my ears and neck down to my shoulders. I'm 29 years old, and if I need opinions on what could it be, and advice also..
