Hi everyone, I have experienced similar symptoms to many on this thread and it had been comforting to read through the comments. In March last year, I experienced a sharp pain in the left of my chest when running - I’m a regular runner, 26, so I know what normal running pain (stitches etc) feel like, and this wasn’t that. It forced me to stop running immediately, the pain subsided and I walked home. Ever since then, this has been a recurring problem - not on every run, but with increasing frequency. If I don’t run for a few days or weeks it might be fine for a couple of runs before returning. In November last year I also had sedentary chest pain for the first time - more of a dull ache, and on a couple of occasions palpatations. I worried (and continue to worry) that this was a more advanced phase of the pain experienced while running. Since November the pain at rest has been near constant - it’s mild during the day so I can continue with my day at possible. It usually gets worse in the evening and when lying down. In the past week my left arm has also constantly ached which I worry is connected. I’ve had an ECG, chest xray and blood tests which have all been fine. My GP has prescribed me Omprezole which I’ve been taking for 2 weeks with no noticeable effect. I’m due to have an arythmia test in February but continue to worry and speculate - it’s taking ages to diagnose largely due the NHS being overwhelmed (I live in the UK). I’m not sure if I have 2 separate issues or if they are connected, nor how serious either could be. But it is affecting my quality of life as it’s stopping me running and the pain at rest is unpleasant.

Any thoughts or advice would be really appreciated. Thanks everyone.
