Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms you are suffering from Gastro-esophageal reflux disease, commonly known as
Acid Reflux and throat tightness, unpleasant taste and burping is due to acid reflux.
Due to acid from stomach refluxing in throat there irritation in throat leading to pain and tightness and the unpleasent taste is due to taste of acid..
Nothing to worry, consult a Gastro-enterologist and get evaluated and if required Endoscopy can be advised to you..
For Acid reflux taking
Proton Pump Inhibitors like
Pantoprazole or
Omeprazole and antacid like
Milk of Magnesia will help..
Drink plenty of water as it help in dilution of acid.
Avoid acidic and spicy foods as well as large heavy meals.
Take small and light meals and eat atleast 2 hours before sleeping..
Take a short walk after meals..
While sleeping keep your head slightly raised as compared to legs..
Take more of probiotics like Yoghurt in diet..
Hope this information helps..
Thanks and regards.
