Thanks Kmn, I know for a fact that it could not have been caused by the nappy as I was sitting up right when I had it stuffed down my top I just fed DD again from that side and it doesn't feel any better. I don't notice it unless my left arm goes across my chest or I lift up my breast from underneath.

Very odd, if I knew what was wrong then I could treat it, I will keep up hot packs and massage etc trying to work it towards my nipple but I don't want to do too much in case thats not it and I cause more pain/damage.

anyone else had this or got any ideas?
