                        This sounds awful.   I don't see where you have mentioned CMV though.  Are you thinking this is related?  I had CMV and was very very sick and told it could come back at any time, but nothing like this.  I hope your son gets better soon.  Sorry I can't help.  Linda  Good Luck
