I have similar pains. But no radiating into the back or gallbladder symptoms. Just burning urine, odd urine flow, fullness in stomach, malaise or fatigue. The ER doctor said I probably had gastritus or a slight chance of having an ulcer. I was on prevacid for 5 days and got ANNOYED with the pills because I felt no different. Is it best that I keep doing the PILLS?? I am scared of the medication reacting with my kidneys or liver like 10 years down the road. Like the antidepressants that people are now figuring out cause kidney failure.
