Hi, I was just diagnosed with a hiatal hernia. It is very painful indeed. I am taking one medication 4 times a day and another one (ppi) 2 times a day.
The one thing I have to say is "get another doc" or make the one you have do his/her job.
You do need to take a lot of life style changes and get a special pillow called a bed wedge (sold at Bath and Body) type stores.
Please become informed because a lot is left up to us. Go to the library and get some books on the subject. There's lots of information on the net too but a book will give you a more comprehensive outlook.
Flares-ups are horrible. Take care
