I have been having what I've been calling 'chest pains' for about 3 years now. First it seemed like a heart problem because the pain was in the middle of my chest but more towards the left side. The pain comes suddenly and randomly. Sometimes I feel stabbing, other times I feel severe pressure. Now, just in the last few months, I've noticed that it has also migrated down under the rib cage right under my left breast. It alternates between the two areas. In addition to the outbursts of pain, most the time I get tired easily, have migraines often, get chills and hot flashes, my limbs fall asleep often, and I'm just not as physically well as a 21 year old, average built woman should be. All routine tests come back fine, blood work is fine, chest xray is supposedly fine, holtor monitor showed no results. Any clues??? Thanks!
