Customer question:
What can cause enlarged lymph nodes? Could enlarged lymph nodes be a cause for concern? Anonymous customer's question
Pharmacist's answer:
Swollen lymph nodes most often indicate a common infection, but they can also signal a medical condition such as an immune disorder or, more rarely, a type of cancer. Swelling occurs as a result of immune cell activity in the lymph nodes.
Symptoms that may be present along with swollen lymph nodes:
- cough
- fatigue
- fever
- fever
- stuffy nose
- sweating
Infections are the most common cause of inflamed lymph nodes. Infections they can cause include:
- ear infection
- sexually transmitted disease
- abscess or impacted tooth
- swelling (inflammation) of the gums (gingivitis)
- colds, flu, and other infections
- mononucleosis
- sores in the mouth
- tonsillitis
- tuberculosis
- skin infections
Some swollen lymph nodes return to normal when the underlying condition, such as a minor infection, improves. See your doctor if you are concerned or have swollen lymph nodes:
- that appeared for no apparent reason
- that are increasing or have been present for two to four weeks
- that feel hard or rubbery or do not move when pressed
- accompanied by persistent fever, night sweats, or unexplained weight loss
Also, seek medical attention if you have trouble swallowing or breathing. The swelling probably results from a non-cancerous condition, but it is best to be sure of this with a proper diagnosis.
