I have no experience so sorry, can't advise BUT thought this may give you something to giggle about to take your mind off it.
My father had a knee replacement two years ago and the district nurse came to the house to take his staples out. One of them was being a bit awkward so she knelt in front of my father and hunched over to get some leverage to it.
Just as she positioned herself my mother walked through the door ...... with the vicar.
Now, the chair my dad was sitting in faces the door at a slight angle and from the door it looked like the nurse had her head buried in my father's lap.
I shall leave the ensuing scene to your imagination :-D
