How soon after ERCP did you get back to ‘normal’ and is this a common post-procedure symptom?

Mom (63, stage IV) got a bile duct stent 3 days ago because she was itching and beginning to jaundice. Right after the procedure, she said her BMs went back to a normal color, as well as her urine. Since then, the itching has gotten better, her skin is returning back to normal (still yellow but less so than before) and her urine has remained lighter. Now, 3 days later she’s mentioning lighter colored BMs again and a random sharp pain (5-6/10) that will come and quickly go away. Wondering if this a normal post-procedure healing pain or if this means the stent is failing and should warrant a doctor appointment?
