I have been experiencing chest pain in between my breasts (feels like breastbone or muscle) It feels like a pulling sensation and only happens at night when I move a certain way..last night the pain radiated from my breast to under my arm. I have no shortness of breath or dizziness. I had bronchitis about 3 weeks ago and mostly over it except still coughing up some mucus. Is the pain I am experiencing from the bronchitis or am I experiencing angina? I do smoke, trying to quit, but it's been difficult but am down to around 5 cigarettes and I am smoking them at night. I took 2 aspirin and the pain subsided.
