Hi. I am a 41 yr old male. I was a runner doing on average 5 -10k every other night with no issues. I came in one night and went to bed as normal. I woke up in the early hours with a sinking feeling in my chest and felt awful for a few days after. I contacted my gp and they did all the usual ecg checks and scans and I am showing an athletic heart rate and blood pressure. It has made it now that I cannot do any exersion at all without this triggering the turns a few hours later. The doctors are baffled. I have w hiatus hernia and I am on nexium. I was perfectly healthy but this has destroyed my normal way of life. Any ideas??.
