Twice since then (once in Sept 2007 and once last week) I have had episodes of excruciating
pain in upper middle section. Feels exactly like the
pain prior to ERCP, as I remember it. Most recent "attack" happened in grocery store about 1 hour after eating. One minute I was fine, the next in terrible pain, sweat pouring off. Pain receded a bit, enough to drive home, only to have it start again in earnest. Entire episode lasted about an hour+. What could this possibly mean?
