Totally health anxious person here - in the last week have had ovarian and breast cancer as well as a brain tumour and skin cancer.
Today I was forced to break into a run - and I am not exactly fit - but after the run I had a stabbing pain in my heart area (left side underneath collar bone at top of breast) for a few seconds. Really winded me.
Last year I was very worried about my hear had an ECG and blood pressure monitored for 24 hours - all normal , cholsterol is good too. I will go see my doc tomorrw but I am freaking out about what the cause of this pain will be!
