I don't think you've ever mentioned this, basically it comes down to you
have to try it and see what happens, some people can breastfeed after breast
surgeries, some people produce milk, but it won't come out, some people
don't even produce milk.

The problem is, all of what you have said can be stuff than new mothers say
anyway and actually do have milk and it is going into the baby, but they
just never see it and that in isolation would not be a reason to think
breastfeeding wasn't working.

There is a possibility that your scar tissue could break down, with
stimulation, but I would think that is unlikely and you'd probably get very
sore in the process of doing it.

as for other things that stop the milk getting out, the main one is skin
growing over the ducts, but it is unlikely to happen to more than one place
at once, it usually results in a plugged duct for the mum and needing to
flick the extra skin off so the milk can flow again, so quite different.
