I had acute pancreatitis mild about 6 months back. Was hospitalized for a week in end march. Ct scan done and it was 2/10 study. Got usg in end april and mrcp in july both normal study. But I am always having uncomfortableness in upper back and mild diffused pain. Don?t need painkillers. This increases as the day goes up. This reduces with rest. I have shown to many specialists but not diagnosed so far. All tests including mri, x ray and blood are normal. Advice please.
