GERD doesn't cure itself. You have to find the cause of the problem.
A camera down the throat doesn't catch everything, and I have no idea why they did a sonogram, looking for tumor maybe. A barium swallow, non-invasive, is pretty good to see what your stomach is doing when you are awake and swallowing and whether the valves are working.
Changing diet and getting rid of bad habits works for some, unless there is a valve problem, which may have been caused by bad habits. Valves don't get better. Sometimes, just sometimes, a contributing problem can be sensitivity to certain foods or chemicals. Look in the archives (search box at the top of the page) for "food journal."
Your stomach makes and needs acid to digest food. The problem comes when it doesn't stay where it's supposed to be. The esophagus is very sensitive to acid and gets "burned." A lot of people take a little acid (vinegar or lemon juice) before eating to tell the stomach not to make so much acid.
If diet doesn't work your doctor may put you on an acid reducer like Zantac. And if that doesn't help the next step is PPIs.
Personally, I was able to live happily with a very bad valve, which needed Zantac and then PPIs, for a long time, because I kept a food journal and found which foods "triggered" my stomach to heave/reflux into my esophagus. Eventually, after 30 years or so, I needed surgery to tighten the valve. I still have to avoid my trigger foods.
