Never had these symptoms so cant really help beyond saying that I take ginger capsules which help me, they give a slightly 'nicer' sort of burning if you get reflux but it is anti inflammatory so may help ease your pain in the long run.
Also I will echo what the poster above said, relaxation helps both physically and mentally! I do autogenics as I had awful anxiety and depression from my stomach/reflux problems and it really helped bring me through that difficult period.
Have you ever been to see a neurologist? I only ask because I read posts from one person that had similar symptoms to you for a long time that normal heartburn treatment didnt relieve and they finally found it was caused by a damaged vertebrae. They reported sharp/burning pains in the throat and neck and I only thought of it because you have these symptoms with your back as well. Is probably worth checking out.
