a few months now i feel breathless, feel to get more air while rushing to work, always feel weak in my chest, feel tired most of time. There is pins and needles in my right shoulder blade. also had totsl recontruction of my right shoulder 10months ago and still pain every now and then, am very busy at work, been busy with my son's weeding which was 8th of april and ocassion was for 4 days. with all this happening does this mean I am still very stressed or do I have heart problem.
