Are my breathing problems and Hiatus Hernia related?

The brathing problem when you have hiatal hérnia is because of the stomach, when goes up, keep pressing tour diaphragm keeping him from expanding properly. Also the hiatal hernia irritates the vagus nerve, wich passes through the stomach and can make you Dizzy and give you a lot of other symptons. Just search for that and you find about It. There are vídeos in YouTube too about that.

I've read through all these posts and can relate to most of them. I am considering surgery after dealing with similar symptoms for 17 months now. I have found some relief on my own, so I will share my story in case it can help anyone else. I'm 37 and living in Los Angeles, so my doctor experiences might be very different. In March 2017, I woke in the middle of the night with shortness of breath and pain that felt like an elephant was on my chest. I literally could not inhale without excruciating pain. It passed gradually, but this continued to happen at least once monthly. I was in and out of the Emergency Room each time - dismissed as having "reactive airway disease." My insurance was bad, so I could not see specialists without a referral...and my doctor took months and months to write any referrals. Aside from the night breathing episodes, I was dealing with other symptoms (tight feeling when swallowing, congestion, raspy voice) - everything indicating LPR. I got to a GI Dr. for endoscopy finally (the anesthesia also did not with for me) & I was diagnosed with a small hiatal hernia (I was never told the size). I was given high doses of PPIs and inhalers to help my breathing. The inhalers helped initially with my breathing, but then they stopped working altogether and I kept ending up back in the ER for breathing treatments - even though I never had wheezing or asthma (just a tight feeling with pain and the sensation of being unable to take a full breath). I took the PPIs but saw zero improvement so I came off them. I started trying to find my own answers since the doctor were not helping. I did a strict diet (I was already underweight when I started the diet, so that was not the cause of my problems). The diet is a high PH diet that can be found online for LPR by searching: "LPR anti-reflux diet voice dr. Koufman." The diet is very strict and I didn't eat for 5 hours before sleep. I also slept sitting up completely at a 90 degree angle for over 9 months. These things helped, but it still wasn't perfect and I still ended up with horrific chest pain episodes that I could not link to any one thing. Those episodes always occurred between 2-3am...which is when our antihistamine production is the lowest and when people usually die in the middle of the night from asthma attacks. On my own I requested a referral to an allergist who did a lot of testing and found nothing...but she gave me Singular, which is an antihistamine known to help with night asthma. I have not had my severe breathing episodes since (2 months)...but I still have shortness of breath all the time, especially if I have a big meal or eat the wrong foods. My diet is VERY strict now and I feel depressed about it (no wheat, no soy, no dairy, and no feeds with a PH below 5.5). I finally have an appointment for lung function testing with a pulmonologist next week (I had to change my insurance to get that scheduled). I am quite certain he will say that my lungs are fine. I feel pretty certain that my HH is causing all of this. I see a chiropractor regularly to manually release my diaphragm and attempt to push my HH back into place. Sometimes it seems to help, not always. Deep diaphragmatic breathing also helps sometimes, not always. Changing sleep positions sometimes helps. Alkaline water has also helped a lot. I read so much about how gaseous pepsin particles from the stomach are refluxed into our lungs with HH, contributing to our breathing problems (I would cough up congestion from my lungs for hours each morning even after sleeping upright all night). It is the pepsin combined with the acid that creates a problem (this eats our healthy tissue). Pepsin cannot survive in a PH above 8. So drinking good quality alkaline water (PH above 8) helped my breathing and stuffiness...I gargled it too and steamed it to breath into my lungs. Now it seems like my symptoms are consistently bad shortness of breath and belching, about 1 week before my menstral cycle... The only thing I can think of is that some hormones cause muscles to relax...perhaps my HH is worse then (if that's even possible?). I know this is similar to how women have heartburn while pregnant due to hormone changes. I still have the pain in the middle of my upper back too - consistent with reflux. Overall I am much better, but I still want to be able to breath normally. Deep diaphragmatic breathing does seem to help along with side sleeping (it's always worse on my back). I would love to get Linx, but I am not a good candidate since my HH is small - but I will request a CT to look at it more closely based on the comments here. Thank you all for some encouragement.
