Introduction
Sore throat and blisters on the lips may be caused by conditions such as cheilitis, tonsillitis, or herpangina. It is important to seek medical attention promptly for diagnosis and to initiate targeted treatment once the cause is identified. Additionally, these symptoms could also result from pharyngitis, hand-foot-and-mouth disease, or shingles. During illness, maintain good personal hygiene, eat a balanced diet, and avoid irritating foods.
Generally, sore throat accompanied by blisters on the lips may be caused by conditions such as cheilitis, tonsillitis, or herpangina. It is important to seek immediate medical evaluation when symptoms appear, identify the underlying cause, and initiate targeted treatment accordingly. Specific analyses are as follows:
1. Cheilitis
In cases of dry weather or inflammatory irritation, the lips may experience prolonged stimulation, leading to symptoms such as sore throat and lip blisters. After onset, medication should be taken according to medical advice. Drugs such as loratadine tablets, levocetirizine hydrochloride dispersible tablets, and erythromycin ointment can help alleviate pain.
2. Tonsillitis
Infection with group A beta-hemolytic streptococcus can adversely affect the tonsils, causing symptoms including sore throat, ulceration, and blisters on the lips. In such cases, consult a doctor for medications such as azithromycin dispersible tablets, Pudilan anti-inflammatory oral liquid, or amoxicillin capsules. In severe cases, tonsillectomy may be considered. Regular follow-up visits at the hospital are recommended after surgery.
3. Herpangina
Infection with Coxsackievirus allows the virus to invade respiratory mucosa via the nasopharynx and oral cavity, resulting in symptoms such as lip swelling, dryness, and sore throat. Antiviral therapy is the primary treatment approach. Medications such as acyclovir tablets, ganciclovir dispersible tablets, and valacyclovir hydrochloride tablets may be taken under medical guidance. Maintaining good oral hygiene is also essential.
In addition, other possible causes include pharyngitis, hand, foot, and mouth disease, and herpes zoster. During illness, maintain personal hygiene, eat a balanced diet, and avoid irritating foods.
