hello my name is derya i am 35 yrs old I ve been having vague symptoms i can t understand chest pain but not persistent sometime the pain hits me from my upper back and sometimes the left side of my chest. my left arm has been aching on and off for some time . I ve also been experiencing jaw pain as well mostly my left side but my right as well . sometimes i have extreme fatigue. lightheadedness . only yesterday as i was walking at a regular pace i started sweating a lot and very short of breath accompanied by a very uncomfortable feeling in my chest like heaviness . sometimes its almost like having a cold and your chest hurts as when you breath cold air. i also feel like my heart keeps skipping a beat but at least 3 times a day and sometimes i feel lightheaded afterwards. these symptoms have been going on for about 2-3 weeks now . i don t have insurance so you can understand why I m not going to the er. i really don t know what to make of all this
