I have chostochondritis and fibermialga. I have been having chest pain, shortness of breath, body pain, feeling of weakness for the past few days. I know that these are all symptoms of these two conditions, however, this morning I started having heart palpitations and while taking my pulse it felt like my heart skipped a few beats. I have also been feeling more tired than usual the last couple of days. Should I be worried about the palpitations considering my two conditions?
