Swollen mesenteric lymph nodes are treated by probiotics, levofloxacin and herbs. When patients do not have acute abdominal pain symptoms, they should not rush to use medicine first, because lymph nodes belong to the immune organs of human body, and when there is abdominal or respiratory tract infection, the immune organs can play the role of resistance to infection, so that the lymph nodes are enlarged. If you have abdominal pain and lymph nodes larger than 10×5 mm, you need to carry out gastrointestinal regulation, and you can take oral probiotics to regulate the intestinal flora, which can play a role in relieving pain. Some patients with enlarged mesenteric lymph nodes are caused by viral infections, which are treated by oral antibiotics and anti-inflammation, such as levofloxacin. It is useful for eliminating local inflammation and relieves the patient’s symptoms. At the same time, you can see a Chinese medicine practitioner and treat the patient with oral herbal medicines for clearing heat and detoxifying, activating blood circulation and relieving pain.
