Thanks for your query,
Probably you are suffering from a disease known as LPRD (laryngopharyngeal reflux disease
) /GERD .All the symptoms you have listed may occur due to that.It occurs due to acid reflux
for long term and it is common during pregnancy
.It is usually treated by PPI for 3 to 6 Months. Proton-pump inhibitors (PPIs) are the most effective medical therapy for patients with moderate-to-severe GERD
and are widely prescribed to pregnant women. However, safety data about the use of these agents during pregnancy or immediately prior to conception are limited . If your symptoms are severe and intractable, i will suggest you to consult a ENT specialist
Hope it helps.
