Diaphragmatic hernia

For the past 5 years,
periodically, sometimes occurring on successive days, and sometimes only every few weeks, I experience severe burning at the juncture of esophagus and stomach - possibly hiatal hernia - but I loathe allopathy and will not see an MD for diagnosis.
When I first experienced these episodes, they were very severe. The first were so severe that I referred to them as "attacks". Over the years, I have researched some and I have followed the advice of a chiropractic friend, using a small hard (rachet) ball pressed firmly below the sternum at the onset. I almost always have to stop whatever I am doing and focus on breath, and leaning my torso over a surface (like a sofa or chair) with the ball firmly placed. More recently I have discovered Mag Phos 6X tissue salt taken immediately at onset and repeatedly dosed over the duration of the episode helps to minimize the pain and the duration. Also I have begun using a therapeutic grade essential oil blend called Di-Tone containing 8 oils that I apply topically to the soft tissue area substernally. I don't know if the relief I am getting is due to the Mag Phos or the essential oils, but these episodes have become much more tolerable. Now I would like some help with understanding how I can totally free myself of these symptoms. Though I have found a method to make them more tolerable, they are still debilitating because I have to discontinue whatever I am doing (and I do have a job) and find a place where I can care for myself. Sometimes the symptoms may take up to an hour before resolved. Sometimes, I get very nauseous and sometimes I will vomit. When this occurs my body will heat up and sweat and I will have to remove clothing. I just joined this forum and have been reading various posts concerning acid reflux and hiatal hernia. I have just learned that Nat Phos may be helpful. Is there a recommendation for a protocal I can follow? Any additional help you can give will be appreciated.
