Yes this is definitely possible, especially When ready feeding as often it's something you've eaten that passes through to your milk and therefore bub.
Hugs to you, it's a frustrating journey, especially when you are dealing with medical professionals who really have no idea!!
Also the screaming can come straight after the feed, I remember my DD screamed right afterwards, horrible! It's definitely a different cry to the 'normal' newborn baby cry, it's a cry of Mum help me! This really hurts!!!
