(UPDATE) As for what the doctor said, apparently they didn't find any more gallstones in my bile duct as it seems any remaining stones were flushed down naturally by my body; however, they did discover that my sphincter was too narrow and therefore my body was unable to consistently flush the bile I was creating down. So they widened it and said it should do the trick. I haven't had any issues with my (non-existent) gallbladder or with eating anything that used to trigger attacks since my surgery in June. Praise God!
Thanks to my Mom and brother for being there and waiting so patiently while this all got done! Back to work again tomorrow!
