The lymphatic system plays an enormous part in our immune system; lymph carries everyday pathogens and allergies to the lymph nodes which act as a filter. When the lymphatic system are compromised they are unable to properly filter out these pathogens which leads to a build-up and destruction of the lymphatic wall. That leads to abnormal accumulation and overloading of interstitial fluid containing high-molecular-weight protein In turn, leading to the deterioration of the lymphatic walls. Just as platelets come and coagulate an injured site on any other part of the body, preventing bleeding or further damage, the same happens with the lymphatic walls when the pressure of the accumulated fluid becomes too much and the walls become compromised, this is called thrombosis. Symptoms we see in patients with thrombosis in the lymphatic walls can be severe, unexplained edema or swelling in areas where lymph nodes are present.
