Treatment for swollen lymph nodes depends on the specific cause, which might include infections, inflammation, tuberculosis, or occasionally more serious disorders. To determine the cause, doctors may recommend blood tests, scans, or occasionally a biopsy. Treatment options may include anti-inflammatory drugs, antibiotics for infections, or more specialised medications if diseases like tuberculosis are discovered. Large, painful, expanding lymph nodes that are connected to fever, weight loss, or persist for several weeks should not be disregarded. For appropriate assessment and treatment, please follow up with your physician or a specialist.
