The right side of the throat hurts when swallowing saliva, and clinically it is mainly seen in the following diseases: 1. Right-sided peri-tonsillitis, such patients will have pain in the right side of the throat, slightly restricted opening of the mouth, and may be accompanied by a painful sensation in the ipsilateral ear. Examination of such a patient reveals congestion of the tonsils, inward displacement of the tonsils, and congestion of the soft palate as well as the anterior arch. In this case, anti-inflammatory and, if necessary, symptomatic treatment with hormones is required. 2. In the case of peri-tonsillar abscesses, the examination of such patients reveals a marked internal displacement of the tonsils, local congestion, and a marked elevation of the anterior arch and soft palate junction area, with pus flowing out when puncture is performed. In individual patients, there is also a bulge between the posterior arch and the tonsil, which may suggest a posterior tonsillar space abscess. In this case, anti-inflammatory treatment, symptomatic treatment with hormones, and incision and drainage of pus are performed.
