Hello! Tbh there’s no much a doctor can do for you.. I am not sure if you engaged any confinement lady? If you do, you can check if she knows how to do postpartum breast massage (I know some do know how to do).. Or signup for postpartum massage? This is part of their deal.
If you do not have any of e above, u can do some massage by yourself but before that u shld use warm compass like 5-10 mins den massage den back to your normal pumping/latch.. U may focus more on e engorged area and do not miss or late for each pumping otherwise it might be more painful..
