They aren't half as bad as you build them up to be, I learnt that from experience....You can ask your OH to do them for you, some people prefer another person to administer them, but I found they hurt more when DH did them so I did them myself.
-But if you really can't do them - Yes, you can request a Community Nurse come and do them for you, but there may not always be one availible. Theres always the option of popping into your GP and having them done there, but this might not be feasible just after giving birth.
I'm sure you'll be fine though!
