Breastfeeding pain

I’m a FTM and gave birth 6 days ago. I’ve been breastfeeding, but oh man, I wish someone warned me about how painful it is! I used to be a G cup before pregnancy, and god knows what they are now but they have gotten HUGE during pregnancy and after giving birth. The swelling hurts so bad and it’s uncomfortable. Breastfeeding itself isn’t too bad but it does hurt quite a bit. I am using nipple butter after breastfeeding. Does this pain go away eventually? Or is it what it is? Any remedies to relieve the pain?
