Change diet: Gerd could be causing your symptoms. Start with eliminating caffeine, alcohol, citrus, nicotine. If still having symptoms, see your family physician or gastroenterologist.

Heartburns: If you have uncontrolled gerd, you can try otc Prilosec 20mg daily (twice a day if once a day is not effective) for 2 weeks. If your symptoms persist, should discuss with your primary care or go see a gastroenterologist.
