If the enlarged lymph nodes under the forehead do not subside, a local color ultrasound should be performed first. Because in some cases it is caused by soft tissue infection, which can occur secondary to a localized cyst or secondary to a viral infection, the patient may also present with localized pain. In such cases, systemic anti-inflammatory therapy or antiviral therapy should be administered. If the patient has a significant fever and a local inflammatory reaction, antipyretic drugs can also be given either oral Merlin or intramuscular lysergic acid. Drink more water during the treatment period, and if necessary, local physical therapy can also be performed, choosing the method of applying heat to the swollen lymph node area to improve local blood circulation, which to a certain extent also has an auxiliary therapeutic effect. If the enlargement does not subside, surgery is required to remove the local lymph nodes and biopsy to determine the type of pathology to guide the next step of treatment.
