You are very welcome, Eliana.

Have you gathered online information from credible institutions (maybe the Mayo Clinic?) about opioid-induced constipation (OIC)?  You are right, it seems OIC is very common, but it may take seeing a gastroenterologist who is an OIC expert to effectively treat it. Based on the little I’ve read about this, it’s very possible that the ER doctors you are dealing with don’t know how to reverse OIC, but that specialists do. The ER doctors you’ve seen should have referred you to a specialist.
