Sick Child not stamping related

So we spent another long night in the Emergency Room, its now 6am and we just got home a little while ago.  We still don't have any answers what is going on with Jacob, tomorrow {Sunday} we have to go back and see the Orthopedic Surgeon's, who knew you can see them on the weekends...I sure didn't.  To try and make a long and complicated story short, Jacob got a viral infection {common cold, flu stuff} and somehow it might of found its way into his hips and knee.  Tomorrow if things do not look good, they will have to take a needle and draw fluid out of his hip and knee, run labs on it, a smear test which you get back right away and a culture which takes a few days.  Another route is to have an MRI done, I don't know how he is going to keep still for an MRI, but its an alternative to scaring him for life about needles.  I just want my baby to feel better and to walk without pain.  This all started about a week and a half ago, he is normally a very active little boy.  It has been a very emotional and tiring week for all of us.  Needless to say I have nothing to show you today, I just wanted to give you an update on what is going on.  I need to go bathe myself in Purrell after spending almost 12 hours in the ER.  Have a great day!
