I am currently 5 days post partum and, beginning yesterday, I began experiencing sharp abdominal pains and vomiting immediately after eating anything. When I have an empty stomach, I have no discomfort whatsoever, and I have no other postpartum complications or discomforts other than some perineal soreness. I had a vaginal delivery with an epidural. Any suggestions? I'm breastfeeding, so I am concerned about my lack of food and water intake.
