ve been having an ache, pressure, with pain on and off under my
left breast or to the
side. tonight its been waking me up
on and off since 1am. i so feel like it has something to do with my heart, like my heart is aching or struggling to work hard. i saw a cardiologist who said i had a normal echo last year so we didnt need to repeat that, and then he did an holter monitor which he said was normal, and ekg that was normal. does anyone know what this pain could be then??
