huh? I'm not real medically smart, but I don't think anyone says, oh yes, I am gonna eat this and this and this, despite that I will get blood clots in my lungs. Sorry your ex friend said that, good reminder why they are an ex-friend.
So what happens now though, can they do anything about this, treatment? And again I am sorry, make sure to take care of yourself!! Is the breathing getting any easier?
