I keep getting pain on my right side of my chest,and up into my throat feels like heart burn. and some times a very bitter taste in my mouth, then clear liquid comes out. this has been happening at least 3 to 4 times a week, and some times twice a day. I have tried Apple cider Vinegar, Tums, Prilosec OTC , and also Heartburn Relief Gummies, nothing works. The pain is very bad.
