Hi, Swollen lymph nodes in the neck area are commonly seen and in most cases, if there are no other symptoms, it doesn’t indicate any disease. However, if there are additional symptoms such as fever, the 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 caused 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 throat, Measles, Ear infections, Infected (abscessed) tooth, Mononucleosis. Mononucleosis is commonest along with the young people and this should be ruled out first. Then it can be treated with antibiotics or other medications depending on the established cause. He should drink more fluids, take ibuprofen and rest as much as possible till symptoms persist. In doubtful cases, lymph nide biopsy can be taken but I don’t think this is necessary at this point. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ivan R. Rommstein, General Surgeon
