Sorry to hear that you are off to the ER. Please let us know what they find and if your doctor has any suggestions for you. Once you find out if you don't have any stones, perhaps just having Mark change your pain medication may help you deal with the pain better. As I said, it seems that the oxycontin seems to help many keep the pain at a lower level than a lot of other opiods and you don't get the sleepiness with them. Also, with the oxy many of us get another prescription for breakthrough pain, this combination seems to help many of us. Good luck.
Love,
