For the last few days I've been having a sharpish pain on one side of my left breast while feeding. At first I suspected my toothy toddler's latch was to blame, but there are no teeth marks, and actually it hurts more than a bit of top teeth leaning on my nipple. I felt around and couldn't identify any taught skin, positioned and no change. There are no lumps, redness, or hot places, no tenderness to the touch when he's not feeding, no nipple soreness.
Any ideas would be greatly appreciated!
