Lymph node swelling, or lymphadenopathy, can be a source of concern for many individuals, especially when they notice new lumps or changes in their body. In your case, you have identified several lymph nodes in your neck that are movable and painless, which is generally a reassuring sign. However, it is essential to understand the potential causes and implications of lymph node enlargement, especially in the context of your recent dental issues with wisdom teeth.

Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which plays a crucial role in the immune response. They filter lymph fluid and help the body fight infections. When lymph nodes swell, it can be due to a variety of reasons, including infections, inflammation, or malignancies. In your situation, the fact that the lymph nodes are painless and movable suggests that they are likely reactive rather than malignant. Reactive lymph nodes often occur in response to infections or inflammation in nearby areas, such as the throat or mouth, which could be related to your wisdom teeth.

The pain you are experiencing near your wisdom teeth could indicate an infection or inflammation in that area, which may lead to the enlargement of nearby lymph nodes as your body responds to the infection. It is not uncommon for lymph nodes to swell in response to dental issues, especially if there is an abscess or gum infection. While it is true that painful lymph nodes are often associated with infections, painless lymphadenopathy can still be a normal response to localized inflammation.

Regarding your concern about the small lumps under your skin in the armpit area, these could be a variety of things, including benign cysts, lipomas (fatty tumors), or even small lymph nodes. Since your family doctor indicated that they are likely not lymph nodes, it may be worth seeking further evaluation if they persist or change in size or appearance.
The sensation of weakness or discomfort in your left arm could be related to several factors, including muscle strain, nerve compression, or even referred pain from your neck or dental issues. It is essential to consider the whole clinical picture, as these symptoms may or may not be directly related to your lymph node swelling.

In summary, while the presence of multiple movable and painless lymph nodes in your neck is generally not alarming, it is essential to monitor any changes. If the lymph nodes become painful, increase in size, or if you develop additional symptoms such as fever, night sweats, or unexplained weight loss, it would be prudent to seek further medical evaluation. Additionally, addressing the dental issues with your wisdom teeth may help alleviate some of the concerns regarding the lymph nodes. Regular follow-ups with your healthcare provider are advisable to ensure that any underlying issues are appropriately managed.
