Welcome to the just answer website.
The most common cause of a sore throat is a viral
infection, such as a cold or the flu.Although most of sore throats are caused by viral infections but the symptoms you have described seems to be most likely due to GERD.It is one of the most common causes of sore throat.
It is a condition in which the esophagus becomes irritated or inflamed because of acid backing up from the stomach.Also there is possibility or H.pylori infection.
Helicobacter pylori (H. pylori) is the bacteria responsible for most ulcers and many cases of stomach inflammation (chronic gastritis) & GERD.Antibiotic medications are used to treat H. pylori infection.You need Urea breath test,blood antibody
test,stool antigen test to detect h.Pylori.
Exact diagnosis can only be made after physical examination.So I advice you to make an appointment with your doctor for tests to know the exact cause & treat accordingly.
