My son had conjunctivitis around 6weeks ago with viral infection,runny nose,sore throat.he had lymph node at side of his neck and still has,is this ok?

It happens...: After a viral or bacterial infection lymph nodes may remain enlarged for weeks. Signs to worry about are if it is hard, does not move when you try to, recurrent fever, sick looking. If no other symptoms I would wait a couple of more weeks and if still the same size then take him to his Pediatrician.

Lymphadenopathy: The ymph nodes become reactive in response to an infection and can take months to resolve completely. That is totally normal.

Common but: A persistent lymph node is worth checking. Sometimes docs prescribe an antibiotic trial. Certainly, your doc can also examine for other problems which could be causing it to persist. Get him seen this week. Most of the time the treatment or observation leads to improvement. If not, further testing is done.
