I'm sorry you are in pain with kidney stones Allen. I don't know if rsd causes more acid, but I can't help but wonder if it does attack our organs in ways such as this. Prior to rsd, I was a 46 year old woman with no history of surgery or major health problems. In the three years I've had rsd I had three surgeries. I lost my ovaries, uteris and cervix to endometriosis and my gallbladder to gallstones. I get constant bladder and urinary tract infections in my stomach. It may be a coincedence, but I don't think so. I know my body and it was perfectly fine until I got rsd. My teeth are all starting to die and get pulled or crack in half. I was feeling much better after my gallbladder surgery four days ago, but today I have that darn acid and nausea again right below my ribcage in the center of my stomach. I have had so much acid in my stomach since rsd, and none before rsd. So I think it could be the rsd causing the acid which is affecting your kidneys. I don't think the meds help, but I think in my case rsd is slowly attacking my body, inside and out. I am now going to call the gastroentrologist to check for an ulcer by getting an endoscopy. Iam also having trouble breathing because of this problem. The last two surgeries I had caused shallow breathing and I was kept in post op longer than usual until it was normal again. I need to see a cardiologist too. But one thing at a time. I hope your kidne ystones don't cause you any pain and that it's not rsd related. I will pray that you feel better soon. From your friend, Renee.
