A person with lymphangitis should be hospitalized and closely monitored by medical professionals.<ref>Prentice, Arnheim's Principles of Athletic Training, 12th edition, pg. 988.</ref> +Lymphatic vessels are smaller than capillaries and tiny venules and are ubiquitous in the body. These vessels are fitted with valves to direct flow in only one direction. Fluid diffusing through the thin walled small capillaries should be collected and the lymphatic system does just that: a fluid rich in protein, minerals, nutrients, and other substances useful for tissue growth. As well as essential nutrients, the lymphatic system can also transport or carry cancer cells, defective or damaged cells, and pathogens such as bacteria and viruses, as well as foreign bodies and organisms. The lymph nodes are found in close proximity to unique white blood cells that engulf or metabolize pathogens (bacteria and viruses) and defective or cancerous cells, preventing infections and malignant cancer cells from spreading. -Lymphangitis is the inflammation of the lymphatic vessels and channels. This is characterized by certain inflammatory conditions of the skin caused by bacterial infections. Thin red lines may be observed running along the course of the lymphatic vessels in the affected area, accompanied by painful enlargement of the nearby [[lymph node]]s. +<ref>{{Cite web|date=2020-11-02|title=Medically Sound: Awash with Protein-rich Fluid, the Lymphatic System Invites for a Direct Invasion by Microbes|url=https://urmedlife.blogspot.com/2020/11/awash-with-protein-rich-fluid-lymphatic.html|access-date=2020-11-07|website=Medically Sound}}</ref>Infection spreads out of the wound site to enter the lymphatic system. The wound may be small or it may be an abscess constantly feeding bacteria into the lymphatic system. After infection, lymph nodes enlarge. Ear, skin, nose, and eye infections can spread into the lymphatic system. Red streak in the skin along the direction of regional lymph nodes indicates lymphatic involvement. Infection may spread within hours and can cause septicemia and death. -When the inferior limbs are affected, the redness of the skin runs over the [[great saphenous vein]] location and confusion can be made with a [[thrombophlebitis]]. +== Symptoms == +<ref>{{Cite web|date=2020-11-02|title=Medically Sound: Awash with Protein-rich Fluid, the Lymphatic System Invites for a Direct Invasion by Microbes|url=https://urmedlife.blogspot.com/2020/11/awash-with-protein-rich-fluid-lymphatic.html|access-date=2020-11-07|website=Medically Sound}}</ref>Warm skin over site of infection.

Malaise, anorxia, tenderness at the site of infection, skin ulcers (rare symptom of lymphangitis), rapid pulse, and enlarged, swollen, and tender lymph nodes. If these symptoms are absent, it is suggestive of other underlying disorders such as tuberculosis, lymphoma, or Hodgkin’s disease.

Bacteria culture is suitable for identifying infectious agents in cases of severe lymphangitis that do not respond well to treatment.   + +Treatment + +Both drug and non-drug based treatment options are available to treat with lymphanginitis. The wound should be treated properly, dead tissues should be removed from the wound site, and pus drained. Applying heat to the affected lymph node using hot, moist compresses, or heating pads. Immobilizing and elevating the affected limb whenever it is possible, and administering analgesics to control pain. + +<ref>{{Cite web|date=2020-11-02|title=Medically Sound: Awash with Protein-rich Fluid, the Lymphatic System Invites for a Direct Invasion by Microbes|url=https://urmedlife.blogspot.com/2020/11/awash-with-protein-rich-fluid-lymphatic.html|access-date=2020-11-07|website=Medically Sound}}</ref>If a local infection is invasive, immediate antibiotic drug therapy is required. Streptococci strains are the most common infectious agents and respond well to cephalosporins –  cephalexin at a dose of 0.5 mg for between 7 and 10 days – or extended-spectrum penicillin. Methiciline-resistant staphylococcus aureus is common in communities and hence the need to use improved antibiotic drugs such as trimethoprim-sulfamethoxazole for 7 to 10 days. Naficillin, oxacillin, and dicloxacillin are also effective against infections of the lymphatic system. ==See also== '
