How big are your stones. It might be dangerous to try to handle this one on your own. Stones that are small enough to easily pass into your pancreas can be fatal c”v . Why don’t you go to a specialist outside of the ER for a consultation and then perhaps go for a second opinion.
Alot of people postpone the surgery with natural stuff for many years and then they end up having to do it anyway. If your a candidate, I would recommend not waiting.
By the way were you terribly itchy in pregnancy?
