I got a tiny little blood blister on my nipple yesterday. I don't think it was the same as a milk blister because I had one of those before and this looked different. It was very small and reddish/clear and sore just at that spot. I gently popped it thinking it would be best to do so and it formed a tiny scab. What I'm wondering is if I should leave the scab alone or pull it off in case it is blocking a duct? I'm worried that if milk isn't being drained then I could get mastitis. Right now it hurts when DS nurses, but not that bad. I just want to make sure this doesn't get worse! So...leave the scab alone or pull it off? I have been rinsing with salt water, putting lansinoh on, and letting it get air...I just can't seem to find anything about what to do about a scab.
