I went to the doctor this week because I was having chest tightness and shortness of breath.  The doc ran several blood tests and determined I had hypothyroidism.  I just started levothyroxine on Wed..  I still am having chest tightness and some pain in my sternum, especially when pressed upon and I do still have some shortness of breath though this comes and goes.  Is this due to the hypothyroidism or should I go back to the doctor and get this checked out?
Hey I think you should get done chest x-ray and SOS bases CT thorax also. It might be related to thymus gland
