I used to get a lot of chest pains and they have definitely decreased since I've been on protonix too (like Lulu). I know the chest pains might not feel like heart burn, but I think sometimes they can be related even if they don't exactly feel like it. If you're not already on something like protonix, you might want to ask your doctor about it especially since you listed GERD as one of your problems. You could also try prilosec otc, but I found that it wasn't quite strong enough for me. I hope that you can get it under control! This pots is a real pain to deal with sometimes, especially with such a wide range of symptoms Oh, and sometimes if the chest pains get really bad, sometimes I find that if you take deep meditative breaths where you expand your diaphragm, it can sometimes help reduce the pain a little. Just a thought... Hope this helps! GOOD LUCK! Lauren
