So in that case, your doctor would perform various diagnostic tests, depending on your other symptoms. According to the Cleveland Clinic, if your lymph nodes are swollen in two or more areas-say, not the two nodes by your jawline, but one by your jaw and one by your armpit or another spot on your body-that could indicate a wider systemic problem. Rarer infections can also spur swollen lymph nodes, such as tuberculosis, toxoplasmosis (a parasitic infection), and some STIs (like HIV or syphilis). A less common infection could be at play. Bacterial infections-for example, strep throat or some cases of pink eye-will require antibiotics to clear things up. But if your symptoms are increasingly uncomfortable, it’s best to reach out to your doctor. Most viral infections, like the common cold, will eventually fade without specific treatment, says Dr. This includes upper respiratory infections, strep throat, ear infections, an infected tooth, measles, mononucleosis, a skin infection, tonsillitis, and pink eye-some of which will likely present with other flu-like symptoms beyond swollen glands or pain and irritation in the affected area. Many common infections, whether they’re short-lived or chronic, can cause swollen lymph nodes, says Dr. A common infection is stirring up symptoms. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security, previously told Prevention. They can appear anywhere after you receive a vaccine, but you’ll likely notice them under your arms or in your neck, which is often near where the injection was, as infectious disease expert Amesh A. So your body is doing what it’s supposed to, and the swollen glands will progressively shrink in size over time (typically in about a week). That’s all part of the normal bodily response. In order for the response to occur, those cells have to expand in number, which causes the nodes to enlarge. “The vaccine creates antibodies in the lymph nodes. “A vaccine replicates what would be a part of the infection without the infection itself,” explains Dr. PIXOLOGICSTUDIO // Getty Images You just received a vaccine.Īny vaccine needs to spark an immune response in order to be effective-including the annual flu shot and the COVID-19 vaccines. Depending on how enlarged they are, swollen lymph nodes may feel like little rubbery nodules the size of a pea, or as big as a cherry or even a plum (either soft and tender or firm). Normally, lymph nodes aren’t visible, but when they’re swollen you may (or may not) be able to see a bump. What do swollen lymph nodes look and feel like? But how can you tell if these enlarged glands are a sign of something more serious? Here’s how to identify swollen lymph nodes, what causes them, and when the symptom actually warrants a visit to your doctor’s office. Swollen lymph nodes are temporary and will eventually resolve on their own, says Dr. This causes swelling to fight off the infection, “and when the job is done they return to their normal size,” says Dr. While the lymphatic fluid is on the move, the immune cells scan for “bad guys”-say, a virus or a bacterium-and if it comes across them, it triggers the nodes to boost the number of their disease-fighting cells. These nodes, which are the size of a pea, are filled with more disease-fighting cells. Along the way, the fluid passes through these bean-shaped (about 600 of them!), which are located in clusters, from your knees up to behind your ears. The vessels of the system are like a highway of one-way lanes lymphatic fluid that’s full of immune cells is pushed throughout your body, according to the Cleveland Clinic.
