stomach pain
I was having pain on my right side and three weeks after my Roux I had to have my gallbladder taken out (also had an obstruction). Definitely talk to your doctor about any odd pains. You could have a bladder infection, kidney infection, kidney stones, gallstones, etc. Don't let me scare you, but for a while your nurses and doctors are there for you in any way and it is never too late to call with problems.
I hope it turns out to be nothing though. Good luck!
