What might cause sore, swollen lymph nodes on one side of the neck?
Swollen lymph nodes on one side of the neck can be caused by infections, such as those spread by ticks, or issues related to the tonsils or submandibular glands.
Explanation
Swollen lymph nodes on one side of the neck can have several causes. One possible reason is an infection, which can lead to swelling in the submandibular glands. These are located under the jaw and can become swollen due to various infections, as discussed by Eleftheriadis et al.
Another potential cause is tick-borne lymphadenopathy (TIBOLA), a condition where a tick bite leads to swollen lymph nodes, as explained by Lakos. This condition can cause the lymph nodes to become sore and enlarged.
Additionally, unilateral tonsillar enlargement, where one tonsil is larger than the other, can also cause swelling of the lymph nodes on one side of the neck. This is explored in the study by Cortez et al.
To summarize, infections, tick bites, and tonsillar issues are some reasons for swollen lymph nodes on one side of the neck. If you experience these symptoms, it is important to consult with a healthcare provider for a proper diagnosis and treatment plan.
