Why you need lymph nodes?
The lymphatic system consists of tiny vessels and large lymphatic ducts that carry lymph throughout the body, and then return it to the lymph nodes – the entities through which the body is cleansed of metabolic products, toxins and pathogens.
Large lipoprotei flow to the veins and contribute lymph, already cleansed from alien elements.
Lymph nodes are entities of dense tissue, resembling the shape of beans. Their sizes can vary from a few millimeters to 2 cm lymph node Groups are located in different parts of the body, to be a barrier to the spread of infection and cancer processes in specific areas of the body. For example, inflammation of the lymph nodes in the leg near groin inflamed lymph node, it indicates pathological changes in the lower extremities or organs located in the pelvis, or the introduction of infection.
How are lymph nodes in the legs, and why are they swollen? How to eliminate the inflammation of lymph nodes and whether to treat conservatively?
Location of lymph nodes in the legs
Why do not all know whether or not the lymph nodes in the legs. Many believe that the last major lymphatic education are located near the groin. The lymph node filters the lymph, as coming from the lower extremities – the legs: feet, shins, thighs, and pelvic area genitalia.
Inguinal lymph nodes are divided into deep and superficial. Surface are in the region of the femoral triangle – the wide fascia of the thigh, on the surface plate. People have different number of lymphoablative from 4 to 20. They are associated with skin and subcutaneous tissue of the perineum and lower extremities, genitalia, anterior abdominal wall.
On the wide fascia of the thigh parallel to the major vessels – veins and arteries – are the deep lymph nodes of the inguinal region. They can be from 2 to 7. They are linked by a deep and superficial lymphatic vessels.
Inguinal nodes help to fight infection the lymph nodes are smaller, located behind the knee. They are"responsible" for the fingers, foot, calf, and thigh.
As you can see, at the junction of the large vessels of the circulatory and lymphatic system is a few "beans", are groups.
Depending on the immune status – high or low – if you get an infection in lymphatic increase may be a single node, locally limiting the spread of infection, or from multiple nodes. In this case, the body may not have enough forces to neutralize the pathogenic flora, and lymphadenitis takes extensive in nature, spreading throughout the body. In this case, without surgery to stop inflammatory process.
Causes inflammation of the lymph nodes in the legs
The lymphatic system in the groin can react on the following factors:
- injury affecting the groin area or the entire foot;
- pronounced acute allergic reactions;
- infection of the skin;
- purulent-inflammatory processes in the lower extremities;
In addition, the group of inguinal nodes become inflamed when infected with sexually transmitted infections, gynecological diseases, prostatitis.
Popliteal lymph nodes react to injuries, common infectious diseases and inflammatory processes below the knee, in cancer processes.
Causes of acute lymphadenitis:
- the introduction of pathogens from the field, which is responsible for lymphoblastoma;
- the spread of infection through the bloodstream.
When inflammation of the lymph node on the leg if inflamed lymph node, over it may be red skin, and touching the affected area will be very painful. If the lymphadenitis is striking the groin, the inflammation could pose a serious threat to the patient. The accumulation of pus causes the formation of cellulitis.
In children, lymphadenitis is more common. His appearance could trigger any disease from seasonal SARS to tuberculosis. The immune system at an early age are very sensitive to invasion of pathogenic flora.
The increase in multiple lymph nodes in adults can be a symptom of the following diseases:
- HIV infection;
Interestingly, with the appearance of the genitals of a chancre – is very characteristic of syphilitic symptoms in the groin there is a significant elevation. But if the lymphadenitis that occurs for other reasons, cause the patient suffering, especially while walking, syphilitic changes painless.
There are other condition is more serious, in which the lymphadenitis of the inguinal region is virtually painless.
The main reasons for the increase in inguinal nodes
What are the disease responds to the lymphatic system of the lower extremities?
- Inguinal lymphadenitis. To eliminate it, you need to detect the focus of inflammation. Most often it is the festering wound on his leg. The disease is treated by means directed against the causative agent, triggering inflammation antifungal or antibacterial drugs. If pus has accumulated in the area of the lymph node, it is necessary to open and drain cleaning of pus;
- Inguinal lymphogranulomatosis. If before this sexually transmitted infection European doctors CIS countries practically did not face – the disease is common in countries with tropical climate – and then after the elimination of the"iron curtain" it is not uncommon. First appears on the skin papule, fluid-filled, and then in its place formed an ulcer, which heals fairly quickly. And after 2 months in men increases the whole group of inguinal lymph nodes, and women-only inflamed the deep nodes in the pelvic area.
To cure the disease is quite difficult, especially to stop the inflammatory process, preferably at a stage until the pus does not spread throughout the body. Special immunological tools help not always. Often have to resort to operational measures and connect chemotherapeutic methods;
- Lymphosarcoma or lymphoma. A malignant tumor develops in the lymphoid tissue, not affecting the blood system. This type of the disease patients are late to seek treatment – at the stage of occurrence of metastasis, as in the beginning of the disease when touching the groin pain does not appear.
Round, dense tumors merge into a conglomerate, fused with the skin, ulcerate, destroy bone marrow.
In oncological processes often require the removal of inguinal lymph nodes.
After removal of inguinal lymph nodes may be complications, as with any operations. It is the inflammation of the surgical site, fever, abscess scar.
But there can be specific consequences of such operations – swelling of the lower extremities. Why do feet swell after removal of inguinal lymph nodes?
Lymphoedema or lymphedema develops almost always after surgery, as it upsets the balance between the removal of the fluid through the lymphatic vessels and capillaries of the fabric itself.
Lymph flow is blocked because the lymphatic system is destroyed. To resolve the complication, drainage of the wound is carried out after the operation for 1-2 months.
The complication is not immediately – to the accumulation of fluid often takes up to 2 months. As soon as the patient notices a slight increase in temperature, bloating in the field of surgery, he should immediately consult the doctor.
No medical procedures to stop the inflammatory process impossible.
It is necessary to monitor the condition of the lymphatic system and inflammation of the nodes, especially if the temperature is increased to consult a doctor. In the initial stages of lymphadenitis function of the lymphatic system is maintained.
If the node has to remove, to eliminate edema of the lower extremities for a long period of time will have to use a special medical linen and to attend massage courses.
