Hello, i have had 2 lympnodes that are enlarged, they dont hurt but i was wondering what could cause this, and if it is a cause for alarm. One is located behind my left ear. I think this one may have become enlarged because of me not taking very much care when gaugeing my ear, this has been here for quite a while, 2 months maybe 3, and hasnt gotten bigger nor smaller. The other lympnode is located on the back of my neck on the left side. i have no idea what this one could be enlarged from, maybe from my peircing yet again. dunno. so please, tel me if this is a cause for alarm or if it is natural for my lymphnodes to be enlarged for and not return to normal.
