Stomach problem. What it is mean?

Throat was burning. I consulted gastroenterology specialist. And i did endoscopy in Dec month.. he said hiatus hernia. Now I'm taking espanz 40 in the night before food and nexpro rd40 in morning before food.. I'm not eating spicy and fried food more.. from Dec month I'm taking this tablets. Rarely i feel like breathing problem also.  When i wakeup in the morning throat irritation will be there daily. I'm taking thyroid tablet 50mg daily for nearly 3 years.. Now my doubt is how long should i continue this nexpro and espanz tablets.. and also why I'm getting this throat irritation in morning alone.. I also consulted ENT specialist also in dec month. He said looks like hasimoto thyroid. What it is mean? My height is 5.5 and weight is 52.
