See i think it's me being paranoid and i kept on feeling the area where i though a lump could be (left of the groin) and it feels like brusing now; there wasnt any swelling beforehand. The one on my neck hasnt changed size at all. Think il just keep an eye on it. Thanks for replying.
Well, anything can happen. There are certain indicators as to whether a bump might be cancer or not: size, rate of growth, shape, feel, presence of pain, etc.
A 2nd opinion would likely be the same in your case. A doc would also have to justify to the insurance company that there is sufficient reason to warrant any testing - which there doesn't seem to be.
Still, it is true that the indicators can always be wrong... which would be so in a very few cases.
There are also reasons why a node might not go down after an infection, such as scar tissue having been formed inside.
There was a thread not too long ago that you can find about a woman who's child had nodes that were enlarged for a long time. Look for--> cat scratch fever, on this forum
Merry Christmas
