Painful letdown

Any mummies still having painful letdowns more than 2 months after birth? Everytime I will experience nausea (feel like vomiting) then top of my breast will hurt and then milk will spray out. I heard it's normal to feel pain during letdown starting of breast feeding journey, but it's been two months and still the same. Though the pain is not a big deal but it's a nuisance. Any idea if there's something wrong?
