Any one had any experience with this? I have been breastfeeding now for 3 weeks and every so often I get a burning sensation in my nipples between feeds (no soreness when feeding). They are also very sensitive to cold, and tender when I brush them with material. Initially I thought this was normal, and was just my nipples getting used to feeding, but then I noticed that when they start burning the tips of my nipples turn white, although they go back to normal colour within a minute. Upon googling it seems to be a case of vaspospasm, but I couldn't find any info on what causes this, or more importantly, what I can do to treat it! Do I go to my GP, HV or breastfeeding counsellor? Or is this something which just goes of its own accord?
