More so as you have symptoms of neck
pain, cold and dry
throat. As the infection resolves, the
nodes will subside. If they are due to causes like lymphomas, other groups of nodes may also be palpable. It would be worthwhile to see if other lymph groups are enlarged namely, axilla and groin, these can be palpated. Also correlate with blood counts, this could lead to further analysis, like for an infection the neutrophils are raised.
Hope this helped and do keep us posted.
