ERCP/ possible stent

I have been in the hospital the past 2 days for an AP flare up. I had an MRI today and the doctor has advised I will be going for an ERCP tomorrow to take a look around and maybe place a stent as they said one of my ducts looks very narrow. They didn’t give me much info on the procedure but I have been reading up on it here and seems like lots of people on here have had bad experiences with both the ERCP and the stent. I have been getting better in the hospital, levels going down and pain is starting to subside and I have also been able to start eating some broth and jello. Just looking for opinions… do you think I should go for the ERCP? Do you think I should decline it for now and wait it out to see if I heal up within the next few days? I just don’t want to have it cause another large flare up. I am also concerned about the stent. Can I tell them I don’t want to have one placed? Any and all advice is welcomed please.
