Hello,
Swollen lymph nodes in neck area are commonly seen and in most cases if there are no other symptoms, it does not indicate any disease. However, if there are additional symptoms such as fever, rapid growth of node, cough,
weight loss, or excessive swelling, then this may be something pathological and require treatment.
In these cases, it is most commonly cause by some sort of infection. The most common cause of swollen lymph nodes is an infection, particularly a viral infection, such as the
common cold.
Other possible causes of swollen lymph nodes include Strep, Measles, Ear infections, Infected (abscessed) tooth,
Mononucleosis. Mononucleosis is commonest along the young people and this should be ruled out first.
Then, it can be treated with antibiotics or other medications depending on established cause. He should drink more fluids, take Ibuprofen and rest as much as possible till symptoms persist. In doubtful cases,
lymph node biopsy can be taken but I do not think this is necessary at this point.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Iven Romanic Rommstein
