when i was pregnant with both my kids [now a 2 yr old & 6 month old] i had very severe rib pain.. it was only in the middle front center of my rib cage as if they were wedged up in there.. i used to feel sore following by ots of pain and as a result from the intense pain my bodys reaction was to get these cold sweats, throw up and nearly pass out.. it only happened at the middle- to end of my pregnanies and stopped as soon as they were out [my son was 8.8lbs and daughter was 9lbs so i had big kids] well now six months later and on my period i noticed i started feeling that soreness in my rib cage.. idk is its because of bad posture or wat..? when my kids were in there the only thing that helped was laying on my left side with a small pillow tucked under my ribs and stretching out as if to give my kids more room.. seems to be helping me right now as welll.. why does this happen to me?
