Wow the way the guy explained it to me was that you would'nt have that risk with an epi??? It only happened with a spinal... good to know you have only seen it once in 6 years though, I did wonder how common it might be, just the fact it has happened to me before worries me but in theroy it should'nt happen to me again (as she pats her back and reassures herself, not helping though!!!)
