I cant Do this anymore

Hello I've tried everything, reflux diet, no coffee, no sugar, nothing to eat 4 hours before bed, pantoprazole and omeprazole nothing helps. Even if I don't eat ANYTHING, my esophagus burns. I really can't do this anymore. Now my doctor said I should see an osteopath; it could be that the reflux is caused by a tense back. I've had a pretty tight back and poor posture for a long time. Has anyone had experience with this and gotten rid of the reflux through proper exercise or through a physiotherapist? This is really my last hope. I had to have the text translated, sorry if there are errors in the text, my native language is German. Thanks
