What is the reason for a pimple on the left lower jaw?

This requires considering whether the swollen lymph nodes are caused by upper respiratory tract infection or other reasons. It usually appears during an acute infection. In most cases, the symptoms disappear after anti-inflammatory treatment. However, in a small number of people, the symptoms never disappear and persist, causing pain and swelling again after infection. It doesn't matter

Causes

1. Infection

Acute and chronic inflammation caused by pathogenic microorganisms, such as bacteria, viruses, rickettsia, etc., such as acute cellulitis, purulent tonsillitis, gingivitis, infectious mononucleosis, scrub typhus, tuberculosis, etc.

2. Tumor

(1) Lymphoma;

(2) Various types of acute and chronic leukemia;

(3) Plasma cell tumors: multiple myeloma, primary macroglobulinemia;

(4) Tumor metastasis: lung cancer, gastric cancer, liver cancer, breast cancer, nasopharyngeal cancer, etc.

3. Reactive hyperplasia

(1) Necrotizing hyperplastic lymphadenopathy;

(2) Serum sickness and serum sickness-like reactions;

(3) Allergic subsepsis;

(4) Systemic lupus erythematosus, rheumatism, etc.

4. Abnormal cell proliferation and metabolism

(1) Langerhans' histiocytosis (histiocytosis X);

(2) lipid storage disease;

(3) Sarcoidosis.

diagnosis

1. Enlargement of lymph nodes in one area is called localized lymphadenopathy, which is often seen in nonspecific lymphadenitis, lymph node tuberculosis and metastasis of malignant tumors. The primary lesion should be found according to the lymphatic drainage area. If lymph nodes are swollen in more than two areas, it should be considered as systemic lymphadenopathy, which is more common in acute and chronic lymphadenitis, infectious mononucleosis, leukemia, lymphoma, leptospirosis, scrub typhus, brucellosis, serum sickness, connective tissue disease, etc.

2. Associated symptoms can provide important clues to the cause of swollen lymph nodes.

(1) Patients with swollen lymph nodes and infection foci in the corresponding drainage areas, such as submandibular and submental lymph nodes with tonsillitis and gingivitis, axillary lymph nodes with mastitis, postauricular lymph nodes with scalp infection, and left inguinal lymph nodes with erysipelas of the left lower limb, can be diagnosed with nonspecific lymphadenitis.

(2) Lymph node enlargement accompanied by pain is usually caused by acute inflammation, often with local redness, swelling, heat and other inflammatory manifestations; while painless lymph node enlargement is common in malignant tumor metastasis, lymphoma, etc. Local lymph node enlargement accompanied by low fever, night sweats, and weight loss may indicate lymph node tuberculosis, malignant lymphoma, or other malignant tumors.

(3) Lymph node enlargement accompanied by periodic fever is often seen in malignant lymphoma; systemic lymph node enlargement accompanied by fever is seen in infectious mononucleosis, leukemia, lymphoma, etc., and occasionally in systemic lupus erythematosus.

(4) Lymph node enlargement accompanied by rash is often seen in certain infectious diseases or allergic diseases, and one should also be alert to lymphoma.
