Regarding buprenorphine 10mg patch. Is?

This is regarding my mother, aged 68 yrs. Concern is, on the day of spine surgery on 13-3-2024 surgeon applied buprenorphine 10 mg patch on upper chest area to overcome post operative pain along with usual intravenous  pain killers  and same buprenorphine 10 mg patch was removed on 19-3-24 and replaced with the new one on that same day and discharged the patient on 19-3-2024 only and after that same patch was still there till date since 19-3-2024 and no pain except mild pain in back area till today and she can walk also with the support now and today we removed that buprenorphine 10 mg patch as well so any worries or any withdrawal symptoms or what?? She is on paracetamol 1000 mg (1-0-1) since 19-3-24 for the pain relief. Earlier for 2 weeks she was on zerodol TH4 as well which was already stopped and paracetamol 1-0-1 is continued till date. Suture removal is also done two days back and surgical site is also healed well. Thanks for your valuable & honest advice
