Hi Thanks for your query. So you have two problems .. firstly you have frequent throat infections and secondly you have acidity. I m sorry but if you have bacterial throat infection then you will have to take antibiotics along with other medicines.There is no permanent cure.You can increase your immunity by increased intake of Vit C inform of plenty of citrous fruits or Vit C tablets. A throat swab culture sensitivity testing along with blood investigations will confirm the diagnosis. For acidity you need to take proton pump inhibitors an hour before having food.Have a healthy easily digestible food.Avoid spicy foods. Do you have acid reflux too ? There might be many causes for this and needs consultation of gastroenterologist. Hope this helps. Update here how you stay. Take care.
