Sorry you continue to have complications and pain and if that's not enough, you have to deal with "the jerk" on a regular basis.
Just an FYI...the procedure is an ERCP...here's a link from NIH:https://www.nlm.nih.gov/medlineplus/ency/article/007479.htm
Tylenol #3 = Tylenol 300 mg and Codeine 30 mg.
My personal opinion is it'll provide more constipation than pain relief...nowhere near the pain relief of oxycodone. It's an ok analgesic for kids and for some mid to maybe moderate orthopedic pain, but for you it's a lousy choice...just my 2 cents.
I hope you get some relief from this stuff...sooner rather than later.
2013 / Diagnosed and successfully treated for hep c geno 1b with Telaprevir, Interferon and Ribavirin...treatment duration 24 weeks.
Retired CRNA (aka nurse anesthetist)...approx 35 years experience in the ER and anesthesia.
Exposure was likely a bloody needle stick from a known hep b patient in 1977. Hep B never progressed to the chronic phase...my own, healthy immune system crushed it.
