I have a 2cm hiatal hernia that is making me very symptomatic and creating Vagus Nerve irritation. Part of my stomach is actually above my diaphragm. I had a consultation with a surgeon and will be having surgery after the GI doctor finishes some "swallow" tests on my esophagus. In the meanwhile, I have to keep dealing with the symptoms (chest pains, arm and neck pains, reflux, abdominal pain, tachycardia,anxiety, and random spasms). I've had two EKG, doctors all say I seem healthy besides all the symptoms I mentioned, and contribute the increased pulse to Vagal nerve irritation. I was originally given Hydroxyzine 50mg and have taken it for about two months. I stopped a few days ago when I was scheduled for an endoscopy and I've been hesitant to start it again. The last time I took it, I had spasms I hadn't had before. My hand actually shook and had major spasms for a few seconds. Is this a side affect of the Hydroxyzine or the Vagus nerve being irritated? I'm so confused and don't know what I should be doing. Would you recommend trying the Hydroxyzine again? Or do you have any recommendations on how to calm the Vagus nerve without it? I read random tricks involving breathing, but I don't want to make anything worse with the hernia. I'm in enough pain already without the Vagus nerve adding to it. PLEASE HELP
