Is it normal that this bump on my head keeps comming back
okay, i am really concerned about this bump behind my ear on my scalp. Well its not really on my scalp, it feels like its underneath. Every once in a while it appears, its small probably the size of a pea? but if i touch it alot it gets bigger. It only hurts when i touch it ,and ive been having this bump on my head issue for about 3 years! it litterly comes and goes, and it only goes away if i dont touch it. Someone said it was from stress but idk.. can it be somthing more serious? And NO I DONT THINK ITS A PIMPLE! Pimples dnt come and go on the same spot for 3 years. I need some answers, is it normal??
