Lymphadenitis can be treated in general internal medicine, general surgery, stomatology and other departments, which need to be selected according to the location of the lymph nodes. There are several groups of lymph nodes in the human body, when you go to the hospital for lymphadenitis, you need to choose the department according to the location of the diseased lymph nodes. For example, if you have cervical lymphadenitis, accompanied by sore throat, fever, nasal congestion, runny nose and other symptoms, you may have upper respiratory tract infections, so you can choose to go to the general internal medicine department. For example, patients with lymphadenitis in the abdomen and inguinal area may choose to go to the general surgery department, while patients with submandibular lymphadenitis accompanied by swollen and painful gums may consider going to the stomatology department. When lymphadenitis occurs, it is recommended to consult the doctor in time, and when it is difficult to choose the department to consult, you can consider the primary disease and consult the department where the primary disease is diagnosed.
