Hi, Kristy-
I have had those symptoms before, and it was due to a hiatal hernia. It is also acid reflux. I thought I was having a heart attack. The pain encompassed my whole upper body, even going up into my lower jaw, ear, and back. There was no relief for it once it got to that point. Just time. After the doctors tested my heart, they did an upper GI on me, and that revealed the problem. I now take one Prilosec OTC (over the counter) every day. It has cured the symptoms. I don't know that it will help if you just take it after the onset of the pain, as opposed to taking it on a daily basis. Also, if this has just recently started, you may be able to even cure it this way. God bless you.
