Inflammation of the tonsils mostly refers to acute tonsillitis, according to its typical clinical manifestations, the disease is not difficult to diagnose. However, attention should be paid to differentiating it from diseases such as pharyngeal diphtheria, Fan Shang pharyngitis and pharyngitis caused by certain blood diseases. The general public lacks the necessary medical knowledge base and diagnostic experience, so it is not recommended to refer to the relevant information to determine whether you have tonsillitis. Symptoms of various types of tonsillitis are similar. Acute kala-azar tonsillitis has mild systemic and localized symptoms. Acute suppurative tonsillitis may start rapidly, and there may be chills, high fever, headache, loss of appetite, fatigue, general malaise, constipation and so on. In children, high fever may cause convulsions, vomiting and lethargy. Severe sore throat is often predominant, often radiating to the ear, accompanied by dysphagia. Submandibular lymph nodes are enlarged, and sometimes one feels inconvenient to turn the head. The patient is acutely ill. The pharyngeal mucosa was diffusely congested, with the tonsils and palatal arches being the most severe. The palatine tonsils were enlarged, and yellowish-white pus spots could be shown on their surfaces, or there were yellowish-white or grayish-white punctate pea-like exudates at the mouth of the crypts, which could be linked together to resemble a pseudomembrane, and the submandibular lymph nodes were often enlarged. In some patients, the pharyngeal cavity can be seen as acute congestion of the palatal arches and tonsils bilaterally, and the tonsils are enlarged to the second degree bilaterally, and scattered pus spots can be seen at the mouth of the crypts. It is recommended that patients go to a specialized hospital to ask the doctor to confirm the diagnosis, not blindly self-diagnosis and treatment, in order to avoid adverse consequences.
