What are the common causes of sore, swollen lymph nodes in the neck?
Swollen lymph nodes in the neck are usually caused by infections, like a cold or sore throat, but they can also be due to more serious conditions.
Explanation
Swollen lymph nodes in the neck, also known as cervical lymphadenopathy, are commonly a response to infections. When you have a cold or sore throat, your body fights the germs, which can make your lymph nodes swell. This is normal and usually goes away once the infection clears.
Here are some common causes:
- Infections: Most often, infections like the common cold, sore throat, or ear infections can cause swelling.
- Other Causes: Sometimes, more serious conditions like certain cancers or immune system diseases can cause lymph nodes to swell.
In rare cases, bacterial infections, such as listeriosis, can also lead to swollen lymph nodes. If the swelling doesn't go away or you feel very sick, it's important to see a doctor.
