Lymph pain, more accurately understood as pain associated with swollen lymph nodes, often signals the body's immune system responding to an infection or other conditions. When lymph nodes swell, especially near an infection, they can become tender and painful as they work to fight off the infection.
Understanding Lymph Nodes and Their Role
Lymph nodes are small, bean-shaped structures located throughout the body. They are part of the lymphatic system, which plays a crucial role in:
- Filtering harmful substances like bacteria and viruses from the body.
- Producing immune cells that help fight infection.
- Draining fluid (lymph) from tissues and returning it to the bloodstream.
Why Do Lymph Nodes Swell and Cause Pain?
According to the provided reference, glands (lymph glands or lymph nodes) swell near an infection to help your body fight it. When the body detects an infection, the lymph nodes in the affected area become more active. This increased activity leads to swelling as immune cells multiply and trap the infection. This swelling can then cause pain and tenderness.
Symptoms Associated with Lymph Node Pain
The pain from swollen lymph nodes can vary in intensity and may be accompanied by other symptoms:
- Tenderness: The affected lymph nodes may be sensitive to the touch.
- Swelling: Noticeable enlargement of the lymph nodes.
- Other Symptoms: As the reference states, other symptoms might include a sore throat, cough, or high temperature, depending on the cause of the lymph node swelling.
Examples of Conditions Causing Lymph Node Pain
- Infections: Common causes include upper respiratory infections, ear infections, or skin infections.
- Inflammation: Conditions that cause widespread inflammation in the body can also cause lymph node swelling.
When to Seek Medical Attention
While swollen lymph nodes are often a sign of a mild infection, it's essential to consult a doctor if:
- The swelling persists for more than a few weeks.
- The lymph nodes are very large, hard, or fixed in place.
- You have other concerning symptoms, such as unexplained weight loss, night sweats, or fever.
