Hi. I ve been having this problem for a week were my chest has been tight up. And my left side felt like there s no weight like it really light. I ve been feeling tried all the time, short of breath, weak. Its been off and on, and now in the last two days my hands and arms are swelled. What s causing this happen?
Thanks for your question on Chat Doctor. In my opinion, as a rule in left sided chest discomfort, wended to rule out cardiac cause first. So get done ECG and 2D Echo to rule out heart related causes. Upper limb edema with shortness of breath and left sided chest discomfort is seen in congestive cardiac failure.  So 2D Echo will rule out this. Other possibilities are anemia and thyroid related problems. So get done CBC to rule out anemia and S.TSH to rule out thyroid related causes.
