Hi..
Welcome to HEALTHCARE MAGIC.
I have gone through your query and can understand your concerns..
As per your complain feeling of something struck in throat while diagnosed with
acid reflux is not an uncommon finding and the feeling is just due to acid reflux and does not look like Sinusitis..
I would suggest you to
consult a Gastroenterologist and get evaluated and if required he can advise you to get another endoscopy done, otherwise it is not needed..
In case if acid reflux is the culprit he can increase the dose of
Omeprazole as well as add antacids like
Calcium carbonate or
milk of magnesia and H2 blockers like Ranitidine..
You can also be advised to avoid spicy food, loose weight if obese, drink plenty of water, add yoghurt to diet, do moderate workout, sleep atleast 2 hours after meals..
Recline on left lateral position as well as keep your head slightly raised while lying down..
Hope this information helps..
Thanks and regards.
