Lymphangitis is an inflammatory disease that occurs in the lymphatic vessels, mostly involving the lymph nodes connected to them, due to a variety of causes. The causes of the disease include infection by pathogens (e.g. bacteria, viruses, parasites, etc.); obstruction of proximal lymphatic drainage due to various reasons, such as congenital developmental anomalies, surgical trauma, and infiltration of cancer cells. Drug treatment should be based on the cause of the disease, as follows: 1. Anti-infection treatment: for bacterial infection, amoxicillin, cefuroxime, levofloxacin and other antibiotics can be taken; for viral infection, acyclovir, ribavirin and other antiviral drugs can be taken; for parasitic infection (such as filariasis) can be taken to ethamizine, albendazole and other drugs. 2. Antipyretic and analgesic drugs: Lymphangitis often leads to pain and fever in the affected area, which can be treated with drugs such as ibuprofen, paracetamol and diclofenac sodium. In addition to medication, you can also use magnesium sulfate wet compresses, physical therapy, surgical treatment and other measures. Patients should use drugs under the guidance of the doctor, do not blindly use drugs.
