On and off for the past 2 months about every week I get a severe pain in my sternum that almost paralyzes me. The pain is so excrutiating that I can not move and I cry. It last for about 2 hours then leaves. It has been happening more frequently, about twice a week now and I'm not sure what is going on. I haven't seen a doctor yet. When the pain subsides I start to get very gassy. When the pain first hits, I feel nauseated and I get hot and cold flashes. Also, it is incredibley hard to breathe, my chest feels tight and if I curl up in a ball it seems to feel a little better but as soon as I stretch out the pain comes back if not doubling what it was before. I'm wondering if anyone else has this problem or any ideas that might help?
