I have been having chest pain, a heaviness with shortness of breath for several months, with symptoms getting worse
. I have dizzy spells, very often during the day, have some pain under the rib area, It seems worse with exertion. I have had a thallium stress test, that showed no blockage, but some irrigularities, don't know what yet, have appointment next week with a cardioligist. On a ER visit, had CT scan with dye, nothing found.
