Hello Im 29, very in shape, non smoker, drink once ever few months. Over the last 9month s or so I ve woken up in the middle of the night with chest pain in my upper right chest almost near my shoulder. They pain also goes down my right arm. Its hurts to breath and I take short breaths. Pains up in rhe 7 out of 10. But last night I was up with the pain it made me be sick. The next few days I can still feel it in my chest like a dull headaches. And its hard too take a deep breath. Only 2weeks ago I had a medical at work. And they said my lungs was 137% Im travelling at the moment and my holiday insurance has ran out. But im back home in the uk free health care in 3months. My question is do you think this is an injury or something up with my right lung. Any help would be great thanks
