About 20 mins ago i started with pain, feels like its in my left breast and left side under my breast.Wen i move, eg i leant forward, the pain got worse, and i just did a little cough and the pain got realtly bad and spread. Then eased up again but stil hurts. Im really worried about my heart as i do get chest aches but this is different, its more of a pain than an ache if that makes sense.
