I have been experiencing pain that sometimes begins in my chest as a dull aching pain and ends up in upper portion of my stomach as a very painful dull ache. Sometimes is almost feels like I can feel a protrusion in middle right below breast bone. I am a little scared as I have just lost my Dad who had a heart attack while recovering from a triple A rupture. Any ideas? I had been taking Prilosec, I really don't think it is helping. I have to double the recommended dose and only sometimes get relief after a few days. I am a 40 year old female, who 2 yrs. ago quit smoking after about 20 years of a pack to pack and half a day. Sometimes upper portion of stomach feels very full, bloated, even if I haven't eaten very much.
