Hi,
Welcome to healthcare magic.
I had gone through your question.
The symptoms strongly suggestive of Laryngopharyngeal disease, that is reflux of
gastric acid into throat leads to constant throat clearing and voice problems.
I recommend the following.
1) Avoid spicy and junk foods.
2) Avoid taking coffee or tea in empty stomach.
3) Take your dinner at least 2 hours before bed time.
4)
Proton pump inhibitor like
rabeprazole is very effective remedy for this condition.
Nothing to worry, you will be fine.
Hope I have answered your question, if you have any questions, you can ask me on healthcare magic.
Wish you a good health.
Regards,
Dr Paparaja S MBBS MS
