For wrapping it back again, you may clean it with the Betadine (which is available without prescription; you may just apply it gently without rubbing on the area) and apply a sterile gauge. Than wrap it with the bandage.
Please feel free for your follow up questions.
Yes, you can use these creams, you have. Just put a small amount good enough to be a thin layer on the removed nail. Than put the sterile gauge and apply the big band aid. A thick layer of the ointment may slip the gauge.
Sorry for the delay. I was on another question. I apologize for your wait.
It is privilege assisting you.
