Question : Hi, about a month 1/2 ago I found a swollen lymph node under my left arm, a day later it was gone. A couple of weeks later I noticed a swollen lymph node under my left ear, which took around 2 weeks go go away. In the past few days I've also noticed a swollen gland under then right side of my neck which comes and goes.

Brief Answer:
Appears to be a normal phenomenon.

Detailed Answer:
Hi,
Lymphnodes get enlarged when there is rise in white blood cells in blood. White blood cells are part of body defence mechanism.
The recurrent enlargement &disappearance of lymphnodes you have suggests infection in upper half &arms of your body.( causes increased white blood cells )..which is been successfully driven out by your defence mechanism...(so the lymph nodes disappear without treatment)This is normal.
If lymph nodes keep on growing,get painful &inflammed or there is generalised persistant lymphnode enlargement through out body ..you need to be concerned.
* At the moment you should be just observant/have a healthy life style /attend any possible recurrent infection in body.
*For a complete assurance..you can get CBC blood test done, to confirm normality of blood cells.
please consult your family physician.
Thanks.
