Hi, 4 days ago I went on a 6 hour flight. 3 hours into that flight I got chest pain. It was a constant ache like someone pushing on my chest. It was annoying and only 2/10 pain. It continued with the occasional heart palpitations. I went to hospital and ECG and cardiac enzymes all negative. I now also feel light headed and tingling down my arms and legs.. They also did chest X-ray which was normal. I just don't feel right and this is so unusual for me. I am 46 and pretty healthy and exercise everyday. I still have a week on this holiday but am seriously thinking of flying home.
