Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that
throat irritation and sour return is not due to infection for which you are advised to take antibiotics and painkillers rather it looks like it is due to Gastro-esophageal Reflux Disease commonly known as Acid reflux..
Due to reflux of acid in throat there is irritation and the sour return is acid refluxing from stomach into throat and at times comes to mouth too..
Nothing to worry, you can
consult a Gastroenterologist and get evaluated and in case of acid reflux you can be advised to take
Proton Pump Inhibitors like
Pantoprazole or Omeprazole, antacids like
Milk of magnesia .
Drink plenty of water and take small meals every 2 to 3 hours.
Avoid spicy,acidic and large,heavy meals.
Eat your dinner 2 hours before sleeping.
Take a short walk after meals.
If you are overweight try loosing weight.
While sleeping keep your head slightly raised as compared to feet and sleep in left lateral position if you wish to sleep laterally..
Hope this information helps..
Thanks and regards.
