I am a 24 yr old female. I noticed I began to get chest, abdominal and back pains after having my son. Before, I was healthy, never had chest pains or anything like this. These flare ups began short and strong. Now a yr later they've become longer and with moderate pain starting in the area between my ribs then expanding to my back. I also get nauscious and have started to throw up. Its terrible, I thought I was having a heart attack but the doctors say I'm fine,my hearts healthy aand to just take over the counter pain killers. Now the pain comes and goes and I still don't know what's causing it. Anyone know what it might be?
