Gastroesoph valvuloplasty

I am scheduled to have surgery with a Dr. At Celebration Hospital on July 5th. It is a pretty new procedure called gastrointestinal valvuloplasty. I had an endoscopy and they found a hiatal hernia 2mm and I also had a ph test that showed I had alot of acid going into my esophagus. My gi dr. Had me go speak to a surgeon to see what my options are. The problems that i have been experiencing is heartburn, burning in my stomach, foggy head, tingling in my arms and legs, hot flashes, cold chills, warm skin. I wake up in the morning with mild anxiety and pain under my ribs and lower esophagus. Has anyone hadbthis surgery and symptoms due to hiatal hernia.
