oh im sorry to hear that, i think your on the right track withs seeing a lactation consultant they could have some great tips for you. Whilst i have never had this happen My sister has and was told its the way she lifts her sons. Are you able to express the milk and maybe feed bubs that way? I remember seeing the discomfort mys ister was in she just persisted. I suggest when ever possible dont use that hand or over stress that part dont put weight on it if possible. I do really hope you can keep with feeding bubs Breast milk but dont be disheartened if you need to stop "mom needs to look after her self first" to look after bubs properly Good luck!
