can gastroparesis due to damaged vagus nerve be helped by a neurologist?

[jimkg]

I suffered damage to the vagus nerve during an abdominal surgery 12 months ago. Since then I had a heart attack and a few weeks ago I developed loud tinnitus. From what I have been able to learn all, the gastric system, the heart, and even the ears are all connected to the vagus nerve. I am at a standstill with gastroenterology and my options are very limited meanwhile my quality of life is severely impacted by these multiple symptoms. I have been researching Vagus Nerve Stimulation but my GI physician says it is ineffective with gastroparesis but I also see it being studied for use to treat tinnitus
