Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms the symptoms that you are suffering from are not due to
Omeprazole but they are due to the
acid reflux itself as still there seems to be acid refluxing from stomach to throat and mouth causing irritation in throat and mouth causing soreness..
As you are scheduled for
endoscopy get it done soon and by the time continue taking Omeprazole and other remedies for relief..
You should take
antacid like
Milk of magnesia half an hour before meals..
Drink plenty of water as it helps in dilution of acid.
Avoid spicy and acidic foods.
Avoid heavy and large meals and take small portions of food every 2 hours.
Eat atleast 2 hours before sleeping..
Take a short walk after meals..
Sleep with head slightly raised as compared to feet.
Hope this information helps..
Thanks and regards.
