I've suffered with This most of 2009 and it's awfull my chest would burn bad from breathing so much .,, it's not like fast breathing it's more over breathing I couldn't think of anything else but my breathing scared me bad ... I got chest pain with it also .. I'll tell u mine just wet away .. But I do have it ATM again alittle and only thing that's helped is to cuff ur hands over ur nose and mouth and breath that way for a few mins try to relax as much as possible it's hard belive me I know ... Do u gt any other symptoms with this. ?
