@Coke train,
I've recently been going thru every test imaginable to rule out heart or lung problems. I'll try to keep this short, but if you need additional info I would welcome questions by PM. I never ever got heartburn, my major symptom for reflux was a constant cough. It was surgically repaired, went exceptionally well, but 2 months after the 1st repair I caught the bug that everyone seemed to get but it made me cough for 4 weeks, which re-ruptured the hernia. I waited 2 years and had the surgery again. Six years later, I know I have a 2 centimeter hernia but the previous surgeries may have caused another condition. Yesterday I had an upper endoscopy that shows everything great, but when they got to my stomach (I consumed no solid food for 16 hours) food was still being retained in my stomach.
I started back with tests when I started having chest pains. I've done every heart test so far and my heart & lungs are fine. Yet I still get chest pains. I will have a few more tests next week, but apparently my stomach lining has now become a problem, no cancerous lesions are expected but benign lesions that may prevent the stomach from emptying into the place it needs to go for normal elimination.
So, yes hiatal hernia can cause chest pain, I can only eat small amounts because I become satiated so quickly, and it might be hours before I can eat anything else.
You might want to contact me thru PM only because I'm guessing most folks don't find internal digestive operations all that interesting. I can at least let you know what my next step will be according to my crack team of medical professionals. I'm just offering it if you are comfortable, I know when we have similar problems its not particularly interesting to others. Good Luck, ColeTrain, txt me if you want. That should be PM me if you like, it's a complicated health problem, maybe we can help each other.
