After having severe rlq pain for 2 months my gi told me to come back in 6 months as she said it could be a virus which caused my mesenteric adenitis. what viruses last up to 6 months that cause mesenteric adenitis?

The mesentery contains the largest amount of lymphatic tissue in the body and those lymph nodes, like others, can become enlarged and tender in response to infections. The best preventive is to eat a healthy mostly plant based high fiber diet so that the bacteria in your intestine (microbiome) are healthy and can protect your lymph nodes which are an important part of your immune system.
