I have had this problem with lymph nodes for a very long time. It's been around for one to one and a half years. Since then there have been no symptoms like it is said to be when something is serious. I first noticed a few lymph nodes on one side of the neck, then they started appearing on the other side. Now I suspect the pain I feel under my arm to be of the other lymph nodes. Just today they even appeared on the back of my thigh. Whenever I go to the doctor most of the time I hear that it isn't anything serious. I do not know what decisions to make for now, can I continue to ignore them or get a few medical scans done? It will be very helpful to get suggestions. Thanks a lot.
