I’m worried about my heart. I have this constant feeling of clunking, jerking, fluttering in my chest. I can’t relax as it’s all I can feel. I have constant gnawing in my ribs directly under my breasts and my head feels odd (best way I can describe it) not a headache but a pressure and a feeling of not being quite right. I’ve had echo, ecgs, chest xray and blood tests over the last year and all normal. Does this sound like heart problems? It’s all I can think about as it’s all I can feel!
