If the pain in the throat is caused by vomiting after drinking alcohol, it may be caused by acute inflammation and congestion of the mucous membrane of the throat due to the irritation of the stomach contents, especially stomach acid, and in severe cases, it may lead to congestion and edema of the mucous membrane of the throat. If the pain in the throat is severe and there is a feeling of obstruction in the throat, you need to go to the otorhinolaryngology department as soon as possible. If the mucous membrane of the throat is only congested and there is no edema, it can be treated with drugs to protect the gastric mucosa. No smoking, no alcohol, no spicy and irritating food. For gastric mucosa-protective drugs, you can use drugs like omeprazole or rabeprazole. However, it is best to visit a specialist in gastroesophageal reflux and be treated under the guidance of a doctor.
