I have severe stomache problems,the first 3 years of having rsd was a night mare,my stomache was the worst issue of all.tried every drug for it.nothing helped.i had nasuea,cramping,cold sweats,eating made it worse.finally my shrink out me in this anti depressant that has a element in it. That helps with the stomache .the drug is called remeron.it changed my life.the stomache issues go away 15 mid after I take it.my stomache isn't normal now bye any means,but it's such a better life with it.it also makes me hungry and will make u sleep too.i take it at night 45 mgs I hope you try this,rsd can destroy the way you feel when it's in your belly.good luck
