Over the last week I have been suffering from a series of symptoms, beginning with a tight feeling in my chest, which progressed to a sharp, stabbing pain in my left shoulder. While the tightness dissipated the next day, the pain lasted for three days. As the pain began to fade, I began to suffer from chills and a low grade fever, which have lasted for four days. Three days ago, I started experiencing palpitations and as of yesterday I have developed a dry cough. The palpitations seem to come and go, although they seem to have intensified with a new tight feeling in my chest. I am 30 years old and overweight, which naturally causes some concern about an underlying heart condition. I have never smoked or taken drugs and I don t drink alcohol. I drink a lot of tea, but never coffee. I am due to see a doctor tomorrow, but as I am an expat living in Russia and there is a language issue, I would really like a second opinion.
