Swollen lymph nodes often signal infection, but certain signs may indicate serious issues:
See a Doctor If:
- Swelling lasts over two weeks.
- There’s unexplained fever, pain, or weight loss.
- The lump grows rapidly or hardens.
Doctors may use exams, imaging, or biopsies to diagnose. Treatments range from antibiotics for infections to chemotherapy or surgery for cancer.
Persistent or unusual lumps require prompt medical attention.
