i am 25 yrs old and i have noticed a swollen lymph node around my groin for over a year now. It is actually moveable,but sometimes it disappears and after a day or so it comes back and often change in size. Over this period , i have not felt any symptoms whatsoever, even when i press the node, i feel no pain....From expert view, i realised it is normal for young adult but my concern is that the node has been there for long without pain or symptoms.please is this normal?
