Pain from the pancreas can be extremely difficult to treat. You appear to have had all the correct investigations and are also on tablets to replace the pancreatic juices. There is no way of predicting whether the pain will improve or not but often it does ease up. I suggest that you see a pain relief doctor who will be able to suggest different ways of tackling the pain rather than just with tablets. As you say, pain from the pancreas can be very severe and I do hope yours will get better.
