Need some advice on hiatal hernia surgery

I am 48, am 128 lbs and 5' 9" (used to be 155lb). I have always been an athlete, play sports and generally healthy. This April starting having breathing issues that hit me like a truck. Prior I had very occasional regurg, like once or twice a year. I ate pretty much whatever I wanted, although I mostly had a very healthy diet. Never had a lot of heartburn and still don't. I have a small hiatal hernia discovered about 5 years ago, which never gave me symptoms. Every doctor says it is still too small to cause problems and GERD (based on a recent Bravo and endoscopy). But I went from 0 to 100 in two weeks this April. Now every day I have symptoms, but some days are better than others, but usually by the end of day is worse. I lost 25 lbs in a matter of weeks and haven't put it back on because I am eating like a bird. Symptoms are bad, breathing difficulties, burping, area under my lower ribs feels like being squeezed like vice and or an expanding balloon, nausea. It is crazy. It is out of nowhere. I am still in the process of trying to figure out if it is the hernia, GERD, or something else. It has been a year of extreme pain and devastation to my quality of life.

So as I explore surgery because medications have done nothing in a year, I would love to know opinions on this as well from those that had the surgery. Link looks very interesting in the sense that you can adjust it or fix where fundoplication seems like get it right or uhoh. There is only so much existing tissue to borrow in the body, so it doesn't seem like the most brilliant solution. Like a win or lose proposition.
