Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. For sore throats occurring only in the evening, you may want to look to your environment--you may be allergic to a pollen, mold or pet dander found in the air. Additionally, the air you breathe may simply be too dry, particularly if you are in a heated home or building in the evening. If outside, external irritants may be the product, including smoke. Sore throat may signal gastroesophageal reflux disease, which sends stomach acids back up the esophagus--this can be intensified after meals, such as dinner. If you enter the evening after intense periods of talking or yelling, you may simply be suffering from muscle strain. Avoid cool drinks and freeze water avoid smoking and caffeine drinks. Use water vapor inhalation and salt water gargling thrice a day for five days. Use tablet Levocetirizine twice a day for five days. If symptoms not improved please consult your doctor he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
