The clinical manifestations of acute tonsillitis include significant pain in the pharynx, aggravation of swallowing, unfavorable swallowing, difficulty in speech and eating, dry burning sensation in the pharynx, and occasional transient reflex earache. Thirst, preference for cool water, fever, headache, fatigue, aching limbs, dry stools, and yellow urine in small amounts. The tongue is usually bright red with a distinct tip. The tonsils can be seen to be congested, enlarged, with yellowish-white pus spots in the crypt, and the lymph nodes in the neck are enlarged with pressure pain. If the infection caused by acute tonsillitis spreads, it can also cause peri-tonsillar abscesses, otitis media, sinusitis, and bronchitis. If the infection is caused by Streptococcus haemolyticus, it is important to pay attention to the complications of the infection, such as rheumatic fever, arthritis and myocarditis. Acute tonsillitis is a more serious infection and requires safe and standardized medication under the guidance of a doctor, not self-administration.
