Hi, I am a 40 year old male. I get a stabbing pain on the outer left side of my chest near my heart. It feels like a deep pain. Though this is just occasionally most of the time it s just a dull ache. The pain can be right across the chest. I get short of breathe and a tight restricting feeling in my chest. I get light headed sometimes to the point of nearly passing out. I feel nauseous and a burning pain across the whole chest which can radiate down my left arm. I have had 2 ecg s both coming up clear. My white blood cell count is up. After 18 months of continual tests after feeling a ripping sensation in my stomach while riding my bike I have recently been diagnosed with 2 hernias, one very low on the right hand side and one very small one near the belly button. I am a very fit person, who runs 5 kms 3 times a week, rides a bicycle twice a week and swims 40 laps once a week. The pain in my chest has been for over a month but has become quite debilitating in the last 2 weeks. The pain isn t just related to exercise I can get it just laying in bed. Any suggestion? Thanks Lee
