I just have to ask, how did you know that that your mesenteric lymph nodes were swollen?
I do know that the lymph system filters the blood, so when we are in treatment, the dead bacteria must be filtered by the lymph system. Sometimes they get clogged and will swell as they are overwhelmed by 'debris' in the blood. Lymph massage is one way to get the lymph glands under the lower jaw and in easily accessible areas to reduce the swelling.
According to this site:
www.wisegeek.org/what-are-the-mesenteric-lymph-nodes.htm"One common cause is a general infection of the large intestine or other parts of the intestinal system from bacterial, viral or parasitic causes. When infection sets in, the lymph nodes often respond by becoming enlarged as they work to fight off the infection. "
As Chloe was suggesting - what are you doing for detoxing? This will be a huge help to the entire lymph system.
