I am 19 weeks pregnant and for the last few weeks I have been experiencing excruciating breast/nipple pain when I go outside. Granted it is particularly cold at the moment but if I am walking to the car I can't drive until it calms down which usually takes a good 5 minutes. It feels like a burning sensation and has bought tears to my eyes. Is anyone else experiencing this problem? I will mention it my midwife when I see her next but in the meantime i would really appreciate any advice.
