GB pain worse after 1st castor oil pack - continue?

My husband's ultrasound shows no gallstones, but he continues to have gallbladder pain since chemo for colon cancer that went to the liver. Tried a castor oil pack and ever since that, pain is excruciating. Do we continue with castor oil packs? It seems liver stones may be stuck in his bile duct. He is afraid of trying a Liver Flush - especially with Epsom Salts . He also has ascites. Tweet
