Similar thing with me Wheeze & glad you shared it with us. I've had chest pains since October. Finally went to the doctor in December who said it was chronic stress but sent me for blood tests & an ECG to be safe. Went to a cardiologist for the results who said the ECG looks unusual. No running or exercise & whisked off to the Rapid Access Chest Unit at hospital. I've had a chest X-Ray & seen the cardiologist there who said my ECG was "grossly abnormal". He confirmed no exercise until I have had a heart scan & angiogram, which I am now waiting for the appointment. Running keeps me sane & reduces my stress, so absolutely gutted & dreading the potential outcome.
