Hi i have been having pains in my chest for several weeks now. Starting a few months ago the pain (like stitch) under both breasts now its predominatley on the left side but also on the right side. I Have had an ECG which showed nothing and i have had blood tests. I don't know what this rules out for a diagnosis. I was also having spells when i thought i was going to faint but never did and feel very heavy like i was being weighed down.The funny spells would go quite quickly but it would result in an upset stomach. Its mainly the chest pains now which seem to be all the time.
