I have acid reflux since 2001 and controlled it with Prevacid until 9/03 when my symptons returned (constant burping, bloated feeling, burning esophaeus). I went on Protonix and I was feeling better again. I stopped taking Protonix 4 months ago & controlled my diet. But 2 months ago my middle chest started feel a little tight and sore and I have a sore throat. I thought it was my Asthma but all tests show that it's not Asthma. I had a ultrasound of the thyroid and that was fine. I was told it may be silent acid reflux. Even though my stomach feels fine I went back on the Protonix a month ago but I haven't improved. Does anyone else have this?
