Refluxing of acid. Or high acid?

I was a smoker before and last month I've been diagnosed with LPRD with chronic granular pharyngitis after the laryngoscopy. I was taking neksium since 40 days and the granules in my pharynx has reduced 80% now and also the post nasal drip and cough has reduced a lot now but still present but the irritation in the larynx and pharynx like burning sensation is still present along with sensation of some mass in throat and pain at times inside throat at different places at different time. Even in last two days while burping I felt like something same near the throat and then the throat became totally dry and scratchy for a very long time then. So should I continue the neksium tab or pan-d for better results? Are they the symptoms of lpr or anything else serious? Can it be due to less acid presence or high acid? Laryngoscopy shows that red dilated vessels has reduced now. Kindly help me to get better.
