hi, I am 15 weeks pregnant and have been experiencing the same problem for about a month and a half. The first couple of times it happened it was both nipples at the same time, unfortunately for me I was outside waiting for a bus, but that didnt stop me from unzipping my coat and sweater so that I could reach in my shirt/bra to put my cold fingers on my nipples, it was the only thing I could do to some-what alleviate the pain. Since then it happens at least once every week and a half and only lasts for about 5, 10 or even 20 minutes sometimes. But last night I was awakened by this burning sensation once again, only this time it was only in my left nipple.
The exact same thing happens, my nipple is hard and does not go down.It burns like its on fire or as if someone heated up a kilt pin and stuck it straight in my nipple. And YES! It is EXCRUCIATING.
I have been looking online for any remedies I could find to sooth the pain.
Here's what I came up with so far.
-One girl said that you can actually buy these tiny round gel packs, you put them in the freezer then in your bra. you can buy them at Target and possibly Walmart.
-Clean them with a warm towel.
-I read that cold doesn't make the pain go away, but hot or warm things do.
(weirdly enough, using a hair dryer really does work!)\
I hope I could help you out, Good Luck!
