please help me fix my hiatal hernia

i have felt uncomfortable my whole life with annoying stomach problems, and have recently been diagnosed with a hiatal hernia. i am sure this is what is wrong with me because i match all of the symptoms. i was told to see a chiropractor to fix it, but he did no good. i was wondering if anyone has had any luck fixing theirs and had any advice for me on what to do. thank you for your help.
