Swollen lymph nodes after a cold are mainly due to a decrease in the body’s resistance and invasion by pathogens, causing an inflammatory response in the mucous membrane of the upper respiratory tract, as well as an active adjacent lymphatic system, resulting in inflammation and swelling of nearby lymph nodes. At this time, blood tests can be performed to clarify the cause of the disease and anti-pathogen treatment, such as anti-bacterial can choose to use drugs such as amoxicillin clavulanate potassium, meloxicillin, cefuroxime, ceftriaxone, cefoperazone sulbactam sodium or levofloxacin. Depending on the severity of the disease, choose to administer the medication orally or by intravenous drip. If accompanied by pain, you can take appropriate antipyretic and analgesic drugs, such as Yuanhu pain relief drops, aspirin and ibuprofen.
