Im suffering from chest pain and shortness of breath. I have had chest xray and this if fine. I have also had an ecg with a normal result. The pain in my chest is quite severe, and seems to come on more in the evenings. I also get the occasional palpitations whilst im having these pains. Im 49 yrs, female, ex smoker. I am having these pains at the moment, and they have been getting worse over the last couple of hours.
