a couple of times over the past 3 weeks ive awoken with a very sharp pain beneath my left rib-cage, sore enough to wake me from sleep. It only lasts a couple of seconds and it goes. Id be fit enough for a 40 year old, never smoked and go for a job 2-3 times a week., but last night i had to stop jogging as I was feeling rough in my chest, like my heart was being over worked. I went to my GP and she sent me to A&E. Whilst there i had bloods, chest x-ray and a stress-test on a treadmill. All came back clear, so I was sent home... problem is that I still don't feel right. I'm just conscious that i wasn't given a diagnosis or reason why the pain was there and my heart didn't feel right. The doctor even suggested Id be fine to run a 5k ive signed up for next week.
Im not sure what else I can do to try and get back to 100%. The doctor did suggest that it could be stress related as I have recently buried my father who died suddenly 3 months ago, but im not a stressful person and generally dont get to stressed about anything.
Any help advice or suggestions would be welcome.
