Labetalol Side Effects - Nipple Pain

I started taking Labetalol today. I felt some side effects within an hour; dizziness, fatigue, skin and scalp chills. These side effects are listed on many sites but what isn’t is nipple pain. I started getting it on both sides as soon as the other symptoms showed up. I asked the nurse and she said it was more likely pregnancy related but I really think it’s linked to the labetalol.

I read a blog from 2013 were some ladies reported having the pain.

Any other ladies take labetalol and has/had this symptom and does it go away?
