Swollen Lymph Nodes: Causes, Symptoms, and Treatment. When you feel a bump or swelling under your skin, it can be concerning. Swollen lymph nodes are one of the most common types of swelling, but what are they exactly? Your lymphatic system is a network of vessels and nodes that helps your body fight infections and disease. Lymph nodes are small, bean-shaped structures that filter lymph fluid and trap harmful substances like bacteria and viruses. When your body is fighting off an infection or illness, your lymph nodes can become swollen as they work to clear out the harmful substances.
While swollen lymph nodes are usually a sign of a minor infection or illness, they can sometimes be a symptom of a more serious condition. It’s important to understand the causes, symptoms, and treatment options for swollen lymph nodes, so you can take the appropriate steps to manage your condition and protect your health.
Swollen lymph nodes can be caused by a wide variety of factors, including infections, cancer, and autoimmune diseases. The symptoms can also vary depending on the underlying cause, so it’s important to pay attention to your body and seek medical attention if you are experiencing persistent swelling or other symptoms. With proper diagnosis and treatment, many cases of swollen lymph nodes can be effectively managed or even cured.
Swollen lymph nodes can be alarming, but they are usually a sign that your body is fighting off an infection. However, in some cases, swollen lymph nodes can be a symptom of a more serious condition, such as cancer or an autoimmune disease. It’s important to understand the causes, symptoms, and treatment options for swollen lymph nodes, so you can take the appropriate steps to manage your condition.
Causes
Swollen lymph nodes can be caused by a variety of factors, including:
- Infections: The most common cause of swollen lymph nodes is an infection. This can include viral infections like the common cold, flu, or mononucleosis, as well as bacterial infections like strep throat or tuberculosis.
- Cancer: Swollen lymph nodes can also be a symptom of cancer. Lymphoma and leukemia are two types of cancer that can cause swollen lymph nodes.
- Autoimmune diseases: Conditions like lupus and rheumatoid arthritis can cause swollen lymph nodes as your body’s immune system attacks healthy tissues.
- Medications: Certain medications, such as antiseizure drugs and antibiotics, can cause swollen lymph nodes as a side effect.
Symptoms
The symptoms of swollen lymph nodes can vary depending on the underlying cause. Common symptoms include:
- Swollen or enlarged lymph nodes that are tender to the touch
- Redness or warmth in the affected area
- Fever or chills
- Fatigue or weakness
- Night sweats
- Unintentional weight loss
- Persistent cough or sore throat
Treatment
The treatment for swollen lymph nodes depends on the underlying cause. If your swollen lymph nodes are caused by an infection, your doctor may prescribe antibiotics or antiviral medications. Over-the-counter pain relievers like ibuprofen or acetaminophen can help relieve pain and reduce fever.
If your swollen lymph nodes are caused by a more serious condition like cancer or an autoimmune disease, your doctor will work with you to develop a treatment plan. This may include chemotherapy, radiation therapy, or surgery.
