You may well expect this result if you were badly congested. It would appear to me that the congestion moved and discharged some infection that has inflamed your biliary system causing the swelling and the pain. It can take up to two weeks for this to settle down. Liver pain is usually a dull grinding pain and acute pancreatitis is unbelievably sharp and it is often difficult to stand with it. When I had it all I could do was lay over a chair until it subsided. You can get relief from pancreatic pain by consuming a tablespoonful of Epsom Salts in a cup of warm water. This doesn't relieve liver pain in the same way so it's a useful diagnostic.
If the discomfort persists then you way attempt another Liver Flush to try a expel the congestion but it is better to wait the two weeks.
