Hi and welcome to HCM.
Some people experience postcholecystectomy syndrome which includes those symtpoms. If this is so extreme as you said further tests should be performed. Many complications can be considered. Abssceses formation or bile duct obstruction
are most common. ULtrasound
is at least what should be done. If she notice fever
or paind under the right ribs she should visit doctor as soon as possible. Also she must follow hepatic diet, drink enough water. PAtches wont help, this is only symptomatic treatment. I suggest to insist on additional tests. blood and liver
lab can show a lot as well.
Wish you good health.
