sphincter of oddi

I was diagnosed with sphincter of oddi dysfunction about 4 years ago. I had an ERCP done,by a wonderful doctor, wich caused a very mild case of pancreatitus (pancreatitis). I was told that it was from the surgery and would not come back so I could eat and drink as normal. It has been four years and it seems my sphincter of oddi is returning. Since it has returned I haven't touched alcohol, knowing that it can make it worse, and have been watching what I eat (I eat healthy anyway). Should I be concerned about damage being done to my pancreas and should I even consider another ERCP? I have RUQ pain and burning which is also in my back, nausea, had a small bit of epigastric pain which didn't last long. I have something most of the time but also have periods where I have no pain. It has been only A week and a half
