Dry cough-Earliear had acid reflux issue

Hello Doctors, From past 1 month am having dry hacking like cough without any other symptoms in between had low fever for 3-4 days, I did all type of fever profile test all were negative, local physician had given some antibiotics that also didn't work, consulted pulmonologist did PFT Xray and IGE test all are normal, still have dry cough, Earlier 3-4 back I had LPR reflux where I was having throat issue feeling like a lump, took PPI for this treatment and my throat sensation became normal, Now for dry cough can it be the same issue. Please suggest. Please suggest PPI for to prevent cough from reflux. I used to take esomeprazole and itopride which worked well. Earlier had tried other combination also but after tak ing esomeprazole and itopride it worked. Please suggest . Thank You.
